We just upgraded our 2sxc custom API to v14, and now we're having an issue in an API controller that's used for uploading files with converting from Base64 to a byte array. Here's the code:
public class IntegrationApiController : Custom.Hybrid.Api14
{
[HttpPost]
public string UploadPdf([FromBody] dynamic bodyJson)
{
var entity = new Dictionary<string, object>();
var guid = Guid.NewGuid();
entity.Add("EntityGuid", guid);
App.Data.Create("PDFForm", entity);
var data = Convert.FromBase64String(bodyJson.file.ToString());
var returnThing = SaveInAdam(stream: new MemoryStream(data), fileName: bodyJson.fileName.ToString(), contentType: "PDFForm", guid: guid, field: "File");
return returnThing.Url;
}
}
We're getting the following error now:
{
"Message": "2sxc Api Controller Finder Error: Error selecting / compiling an API controller. Check event-log, code and inner exception. ",
"ExceptionMessage": "c:\\Websites\\Mainstar\\Portals\\0\\2sxc\\DocusignForms\\api\\IntegrationApiController.cs(26): error CS1061: 'ToSic.Sxc.Services.IConvertService' does not contain a definition for 'FromBase64String' and no extension method 'FromBase64String' accepting a first argument of type 'ToSic.Sxc.Services.IConvertService' could be found (are you missing a using directive or an assembly reference?)",

}
Any ideas how to fix this? I did try changing "Convert.FromBase64String" to "System.Convert.FromBase64String" and that didn't solve the issue - I got a "Cannot perform runtime binding on a null reference" error instead.
Any help would be greatly appreciated!
System.Convert... sounds right. And IMHO should work.
My guess is that your bodyJson or bodyJson.file is null.

I came across this error when modifying a DB first project (using fluent migrator) and scaffolding the EF context to generate models. I have reproduced it by making a code-first simplification. This means that I can't accept answers that suggest modifying the annotations or fluent configuration, because this will be deleted and recreated on the next migration and scaffold.
The simplified idea is that a device has:
many attributes
many histories representing changes to the device over time
each history entry has an optional location
IOW you can move a device around to locations (or no location) and keep track of that over time.
The code-first model I came up with to simulate this is as follows:
public class ApiContext : DbContext
{
public ApiContext(DbContextOptions<ApiContext> options) : base(options) { }
public DbSet<Device> Devices { get; set; }
public DbSet<History> Histories { get; set; }
public DbSet<Location> Locations { get; set; }
}
public class Device
{
public int DeviceId { get; set; }
public string DeviceName { get; set; }
public List<History> Histories { get; } = new List<History>();
public List<Attribute> Attributes { get; } = new List<Attribute>();
}
public class History
{
public int HistoryId { get; set; }
public DateTime DateFrom { get; set; }
public string State { get; set; }
public int DeviceId { get; set; }
public Device Device { get; set; }
public int? LocationId { get; set; }
public Location Location { get; set; }
}
public class Attribute
{
public int AttributeId { get; set; }
public string Name { get; set; }
public int DeviceId { get; set; }
public Device Device { get; set; }
}
public class Location
{
public int LocationId { get; set; }
public string LocationName { get; set; }
public List<History> Histories { get; } = new List<History>();
}
Running the following query to select all devices works fine. I'm using a filtered include to only select the most recent history for this "view":
var devices = _apiContext.Devices.AsNoTracking()
.Include(d => d.Histories.OrderByDescending(h => h.DateFrom).Take(1))
.ThenInclude(h => h.Location)
.Include(d => d.Attributes)
.Select(d => d.ToModel()).ToList();
that works fine, however when I try and select only one device by ID using the same includes:
var device = _apiContext.Devices.AsNoTracking()
.Include(d => d.Histories.OrderByDescending(h => h.DateFrom).Take(1))
.ThenInclude(h => h.Location)
.Include(d => d.Attributes)
.First(d => d.DeviceId == deviceId)
.ToModel();
I get the following error:

I can't figure out why this is working for a number of rows but not working for a single row.
For completeness, ToModel() is just an extension method to return a POCO.
I'm not even sure where to start looking, ideas welcome!
Edit
bug report: https://github.com/dotnet/efcore/issues/26585
repro: https://github.com/thinkOfaNumber/efcore-5-test
Update: The bug is fixed in EF Core 6.0, so the next applies to EF Core 5.0 only.
Looks like you have hit EF Core 5.0 query translation bug, so I would suggest to seek/report it to EF Core GitHub issue tracker.
From what I can tell, it's caused by "pushing down" the root query as subquery because of the Take operator (which is basically what First method is using in the second case). This somehow messes up the generated subquery aliases and leads to invalid SQL.
It can be seen by comparing the generated SQL for the first query
SELECT [d].[DeviceId], [d].[DeviceName], [t0].[HistoryId], [t0].[DateFrom], [t0].[DeviceId], [t0].[LocationId], [t0].[State], [t0].[LocationId0], [t0].[LocationName], [a].[AttributeId], [a].[DeviceId], [a].[Name]
FROM [Devices] AS [d]
OUTER APPLY (
SELECT [t].[HistoryId], [t].[DateFrom], [t].[DeviceId], [t].[LocationId], [t].[State], [l].[LocationId] AS [LocationId0], [l].[LocationName]
FROM (
SELECT TOP(1) [h].[HistoryId], [h].[DateFrom], [h].[DeviceId], [h].[LocationId], [h].[State]
FROM [Histories] AS [h]
WHERE [d].[DeviceId] = [h].[DeviceId]
ORDER BY [h].[DateFrom] DESC
) AS [t]
LEFT JOIN [Locations] AS [l] ON [t].[LocationId] = [l].[LocationId]
) AS [t0]
LEFT JOIN [Attribute] AS [a] ON [d].[DeviceId] = [a].[DeviceId]
ORDER BY [d].[DeviceId], [t0].[DateFrom] DESC, [t0].[HistoryId], [t0].[LocationId0], [a].[AttributeId]
and for the second (or just inserting .Where(d => d.DeviceId == deviceId).Take(1) before Select in the first):
SELECT [t].[DeviceId], [t].[DeviceName], [t1].[HistoryId], [t1].[DateFrom], [t1].[DeviceId], [t1].[LocationId], [t1].[State], [t1].[LocationId0], [t1].[LocationName], [a].[AttributeId], [a].[DeviceId], [a].[Name]
FROM (
SELECT TOP(1) [d].[DeviceId], [d].[DeviceName]
FROM [Devices] AS [d]
WHERE [d].[DeviceId] = #__deviceId_0
) AS [t]
OUTER APPLY (
SELECT [t].[HistoryId], [t].[DateFrom], [t].[DeviceId], [t].[LocationId], [t].[State], [l].[LocationId] AS [LocationId0], [l].[LocationName]
FROM (
SELECT TOP(1) [h].[HistoryId], [h].[DateFrom], [h].[DeviceId], [h].[LocationId], [h].[State]
FROM [Histories] AS [h]
WHERE [t].[DeviceId] = [h].[DeviceId]
ORDER BY [h].[DateFrom] DESC
) AS [t0]
LEFT JOIN [Locations] AS [l] ON [t].[LocationId] = [l].[LocationId]
) AS [t1]
LEFT JOIN [Attribute] AS [a] ON [t].[DeviceId] = [a].[DeviceId]
ORDER BY [t].[DeviceId], [t1].[DateFrom] DESC, [t1].[HistoryId], [t1].[LocationId0], [a].[AttributeId]
Note the usage of [t] in the first SELECT [t].[HistoryId]... inside the OUTER APPLY, which in the fist query is alias to the inner Histories subquery in FROM clause, while in second it is alias to the outer Devices subquery, which of couse have no columns mentioned in the error message. Apparently in the second case [t0] should have been used.
Since it is a bug, you have to wait it to be fixed. Until then, the workaround I could suggest is to explicitly execute row limiting operator (First) outside of the EF Core query context, e.g.
var device = _apiContext.Devices.AsNoTracking()
.Include(d => d.Histories.OrderByDescending(h => h.DateFrom).Take(1))
.ThenInclude(h => h.Location)
.Include(d => d.Attributes)
.Where(d => d.DeviceId == deviceId) // instead of .First(d => d.DeviceId == deviceId)
.AsEnumerable() // switch to client evaluation (LINQ to Objects context)
.First() // and execute `First` here
.ToModel();
I am using Dapper to query a table that includes an XML field:
CREATE TABLE Workflow
(
Guid uniqueidentifier not null,
State xml not null
)
which is then mapped to a property of type XDocument:
public class Workflow
{
public Guid InstanceId { get;set; }
public XDocument State { get;set; }
}
but when I try to query the table, I get the following error:
Error parsing column 1 (State= - String)

Other than modifying my POCO to use a string datatype and then convert the string into an XDocument elsewhere, is there a way of getting Dapper to correctly deserialise the XML from the database?
In the end, I just brute-forced it:
public class Workflow
{
public Guid InstanceId { get;set; }
public XDocument StateIn { set { State = value.ToString(); } }
public string State { get;set; }
public XDocument StateOut { get { return XDocument.Parse(State); } }
}
Dapper plays with the State value, and I just set the value on StateIn and read it off StateOut. I feel a little bit dirty coming up with a solution like this, but hey, it works.
Perhaps creating a custom type handler can help? Something like:
public class XDocumentTypeHandler : SqlMapper.TypeHandler<XDocument>
{
public override void SetValue(IDbDataParameter parameter, XDocument value)
{
// set value in db parameter.
}
public XDocument Parse(object value)
{
// parse value from db to an XDocument.
}
}
You have to add the type handler with SqlMapper.AddTypeHandler().
See a sample implementation.

I had this issue because the directories NHibernate.Cache.StandardQueryCache and UpdateTimestampsCache in the executable directory got out of date.
However, that lead to the next issue -- I couldn't install under Program Files because NHibernate attempted to create these directories on first run.
I'm in need of importing CSV data from a client computer to a SQL Server which exists elsewhere on the network. I want to do this with PowerShell as I'm trying to become more fluent in using it.
However, when I use an example I've found on the internet I've run into an issue which I don't understand.
For reference I'm using the third example from:
http://blogs.technet.com/b/heyscriptingguy/archive/2011/11/28/four-easy-ways-to-import-csv-files-to-sql-server-with-powershell.aspx

The innermost exception is the issue.
Your Module type needs a parameter called "screenFactoryRegistry" of type IScreenFactoryRegistry. Since IScreenFactoryRegistry is an interface and you apparently have not done a Register in the container to map that interface to a concrete type, the Unity container throws an exception.
To resolve this, you'd need to map that type in Unity, probably in the ConfigureContainer method of your bootstrapper:
Container.RegisterType<IScreenFactoryRegistry, MyScreenFactoryRegistryImplementation>();
