Cores fail when trying to add requestHandler in Solr - solr

Question

I am new to Solr and am trying to add the Suggest Search Component via the Config API.
My Solr 9.0.0 setup is as follows:
bin/solr start -e cloud with _default config
Add the search component with a POST request to http://localhost:8983/api/collections/collection_name/config:
{
"add-searchcomponent": {
"name": "suggest",
"class": "solr.SuggestComponent",
"lookupImpl": "FuzzyLookupFactory",
"dictionaryImpl": "DocumentDictionaryFactory",
"field": "name",
"suggestAnalyzerFieldType": "string",
"buildOnStartup": "false"
}
}
Until here everything is fine and I receive a responseHeader with status 0.
Add the request handler with a POST request to http://localhost:8983/api/collections/collection_name/config:
{
"add-requesthandler": {
"name": "/suggest",
"class": "solr.SearchHandler",
"defaults": {
"suggest": "true",
"rows": "10"
},
"components": "suggest"
}
}
In step 3 I receive a responseHeader with status 500 and the following error message:
1 out of 2 the property overlay to be of version 4 within 30 seconds! Failed cores: [http://localhost:8983/solr/collection_name1_replica_n1/]
What am I doing wrong?

Answer 1

I could solve it. My error was not adding “components” in the add-requesthandler as an array.
original:
{
"add-requesthandler": {
"name": "/suggest",
"class": "solr.SearchHandler",
"defaults": {
"suggest": "true",
"rows": "10"
},
"components": "suggest"
}
}
correct:
{
"add-requesthandler": {
"name": "/suggest",
"class": "solr.SearchHandler",
"defaults": {
"suggest": "true",
"rows": "10"
},
"components": [“suggest"]
}
}
