I have LogicApp which get HTTP Post from Azure Alerts.
I would like to create "DimensionNames" string variable, which includes all names in array.
DimensionNames value could be "name1,name2, name3, name4".
Finally I would use DimenstionNames string in "call Webhook".
How do it?
Request Body Json in "When a HTTP request is received"
{
"dimensions": {
"items": {
"properties": {
"name": {
"type": "string"
},
"value": {
"type": "string"
}
},
"required": [
"name",
"value"
],
"type": "object"
},
"type": "array"
}
}
Using variables and Join action you can convert array to a string variable. I have reproduced from my side and below are steps I followed,
Created an alert and configured a HTTP trigger logic app to it.
Designer of logic app will be,
The payload of http request is,
{
"dimensions": {
"items": {
"properties": {
"name": {
"type": "string"
},
"value": {
"type": "string"
}
},
"required": [
"name",
"value"
],
"type": "object"
},
"type": "array"
}
}
4. Next taken Initialize variable action as shown below,
Taken Join action to divide values from array with comma,
Next taken another initialize variable action to store value as a string,
In webhook action the value of string variable is used as body,
Outputs are shown below,
Http trigger:
Output of initialize variable,
Output if Join,
Output of initialize variable 2,

I'm trying to write a json validator to check files before runtime but there's a really odd issue happening with using "type".
I know "type" is a reserved word but jsonSchema doesn't have an issue with it if it doesn't have a value pairing as I found in this other question: Key values of 'key' and 'type' in json schema.
The solution to their problem was encasing "type": { "type": "string"} inside "properties" and it does work. However, my implementation requires it to be inside an array. Here's the snippet of my code:
{
"type": "object",
"additionalProperties": false,
"properties":{
"method":{
"type": "array",
"items":{
"type": {
"type": "string"
},
"name":{
"type": "string"
},
"provider": {
"type": "array"
}
}
}
}
}
Oddly enough, VScode doesn't have a problem with it in a file when it's isolated, but when it's included in the main code, it doeesn't like it and yields no solution. Regardless, validating it with python yields:
...
raise exceptions.SchemaError.create_from(error)
jsonschema.exceptions.SchemaError: {'type': 'string'} is not valid under any of the given schemas
Failed validating 'anyOf' in metaschema['allOf'][1]['properties']['properties']['additionalProperties']['$dynamicRef']['allOf'][1]['properties']['items']['$dynamicRef']['allOf'][3]['properties']['type']:
{'anyOf': [{'$ref': '#/$defs/simpleTypes'},
{'items': {'$ref': '#/$defs/simpleTypes'},
'minItems': 1,
'type': 'array',
'uniqueItems': True}]}
On schema['properties']['method']['items']['type']:
{'type': 'string'}
What further confuses me is that https://www.jsonschemavalidator.net/ tells me
Expected array or string for 'type', got StartObject. Path 'properties.method.items.type', line 8, position 17. yet JSON Schema Faker is able to generate a fake file without any problems. The generated fake json also returns the same error when validated with python and JSONSchemaValidator.
I'm a beginner and any help or insight will be greatly appreciated, thanks for your time.
Edit: here's the snippet of the input data as requested.
{
...
"method": [
{
"type": "action",
"name": "name of the chaos experiment to use here",
"provider": [
]
}
}
]
}
Arrays don't have properties; arrays have items. The schema as you have included it is not valid; are you sure you don't mean to have this?
{
"type": "object",
"additionalProperties": false,
"properties":{
"method":{
"type": "array",
"items":{
"type": "object",
"properties": {
"type": {
"type": "string"
},
"name":{
"type": "string"
},
"provider": {
"type": "array"
}
}
}
}
}
}
I'm creating a json schema to define necessary data with data types. There is some data need to be set into required filed. But didn't find how to do it in its document.
For this json schema:
{
"type": "object",
"required": [
"version",
"categories"
],
"properties": {
"version": {
"type": "string",
"minLength": 1,
"maxLength": 1
},
"categories": {
"type": "array",
"items": [
{
"title": {
"type": "string",
"minLength": 1
},
"body": {
"type": "string",
"minLength": 1
}
}
]
}
}
}
json like
{
"version":"1",
"categories":[
{
"title":"First",
"body":"Good"
},
{
"title":"Second",
"body":"Bad"
}
]
}
I want to set title to be required, too. It's in a sub array. How to set it in json schema?
There are a few things wrong with your schema. I'm going to assume you're using JSON Schema draft 2019-09.
First, you want items to be an object, not an array, as you want it to apply to every item in the array.
If "items" is a schema, validation succeeds if all elements in the
array successfully validate against that schema.
If "items" is an array of schemas, validation succeeds if each
element of the instance validates against the schema at the same
position, if any.
https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-02#section-9.3.1.1
Second, if the value of items should be a schema, you need to treat it like a schema in its own right.
If we take the item from your items array as a schema, it doesn't actually do anything, and you need to nest it in a properties keyword...
{
"properties": {
"title": {
"type": "string",
"minLength": 1
},
"body": {
"type": "string",
"minLength": 1
}
}
}
Finally, now your items keyword value is a schema (subschema), you can add any keywords you can normally use, such as required, the same as you have done previously.
{
"required": [
"title"
],
"properties": {
...
}
}
I created a simple logic app triggered by sending a json payload and I need to retrieve a value of a property in order to use it in a condition scope.
Thanks for you help
Please use Parse Json action, please click Use sample payload to generate schema, and then paste your json to generate the schema needed to parse the json:
Then select the key of the value you want to get
===============update=============================
I defined a json string as input.
According to the json string you provided, the generated schema should look like this：
{
"properties": {
"CusttId": {
"type": "string"
},
"Direction": {
"type": "string"
},
"MyId": {
"type": "string"
},
"Reason": {
"type": "string"
},
"TestDateTime": {
"type": "string"
}
},
"type": "object"
}
I did a test and it can retrieve MyId:
Here's my json - Here I want to retrieve json content from "Property - Dynamic content". Where, dynamic content part might vary for every json request. How do I filter this by a dynamic name?
{
"Attributes":
{
"Property1": {
"Data1": {
"Value": "50"
}
},
"Property2": {
"Data2": {
"Value": "50"
}
},
"Property - Dynamic content": {
"Data3": {
"Value": "50"
},
"Data4": {
"Value": "50"
}
}
}
}
For your requirement, please refer to my logic app below:
1. I initialized a variable and store the json same with yours to simulate your situation.
2. Then use "Parse JSON".
Please notice the schema of "Parse JSON" show as:
{
"properties": {
"Attributes": {
"properties": {
"Property - Dynamic content": {
"type": [
"object",
"array"
]
},
"Property1": {
"properties": {
"Data1": {
"properties": {
"Value": {
"type": "string"
}
},
"type": "object"
}
},
"type": "object"
},
"Property2": {
"properties": {
"Data2": {
"properties": {
"Value": {
"type": "string"
}
},
"type": "object"
}
},
"type": "object"
}
},
"type": "object"
}
},
"type": "object"
}
Please pay attention to the type of Property - Dynamic content in schema above. Since the content of Property - Dynamic content is either "object" or "array", so I set both "object" and "array" as the type of Property - Dynamic content.
3. Then I initialized a variable named "result" to get the value which you want.
As we use both type "object" and "array" in the schema for Property - Dynamic content, so you may not find it in the "Dynamic content" selection. You can input its value by expression as the screenshot above. The whole expression is: body('Parse_JSON')?['Attributes']?['Property - Dynamic content']
I was able to get what I need using inline code - javascript - If anyone else is looking for the same - here it is - This will give json from Property - dynamic content element.
var data = Object.keys(workflowContext.trigger.outputs.body.Attributes);
var key = data.filter(s => s.includes('Property')).toString(); // to get element - Property - dynamic content
return workflowContext.trigger.outputs.body.Attributes[key];
I'm writing a simple JSON schema and using minItems to validate the number of items in a given array. My schema is as follows:
{
"title": "My Schema",
"type": "object",
"properties": {
"root": {
"type": "array",
"properties": {
"id": {
"type": "string"
},
"myarray": {
"type": "array",
"items": {
"type": "string"
},
"minItems": 4,
"uniqueItems": true
},
"boolean": {
"type": "boolean"
}
},
"required": ["id","myarray","boolean"]
}
},
"required": [
"root"
],
"additionalProperties": false
}
Now I would expect the following JSON to fail validation given the element myarray has nothing in it. But when using this online validator, it passes. Have I done something wrong or is the schema validator I'm using faulty?
{
"root":[
{
"id":"1234567890",
"myarray":[],
"boolean":true
}
]
}
I am not sure why or what it is called, but the correct schema definition for your requirement should be as shown further down.
From what I understand from the JSON Schema definitions, you should declare the properties of an array inside the items declaration. In your schema you where defining properties outside of the array item declaration.
In your schema you have the two different types of array declaration:
Once with just a single object (a string for the "myarray" object)
Once with a complex object (the object name "myComplexType" in the code below)
Have a look at the definitions of both, how they are structured and how they would be interpreted.
The corrected schema:
{
"title": "My Schema",
"type": "object",
"properties": {
"root": {
"type": "array",
"items": { <-- Difference here - "items" instead of "properties"
"type": "object", <-- here - define the array items as a complex object
"title": "myComplexType", <-- here - named for easier referencing
"properties": { <-- and here - now we can define the actual properties of the object
"id": {
"type": "string"
},
"myarray": {
"type": "array",
"items": {
"type": "string"
},
"minItems": 4,
"uniqueItems": true
},
"boolean": {
"type": "boolean"
}
}
},
"required": [
"id",
"myarray",
"boolean"
]
}
},
"required": [
"root"
],
"additionalProperties": false
}
Remove the comments I added with <-- when copying over to your code, added for pointing where there changes are.
As a note, I do however don't understand why the validator didn't give an error for the 'malformed' schema, but might just be that it saw the definition as you had it as additional properties, not entirely sure.
The only thing wrong with your schema is that the root property should have type object instead of array. Because the properties keyword is not defined for arrays, it is ignored. Therefore, the part of the schema you were trying to test was completely ignored even though it was correct.
Here is the relevant passage from the specification
Some validation keywords only apply to one or more primitive types. When the primitive type of the instance cannot be validated by a given keyword, validation for this keyword and instance SHOULD succeed.
