Unable to copy a custom trained Form Recognizer model using the "azure-sdk-for-net" version 4.0.0

Question

I am currently using the azure-sdk-for-net readme as a reference to try and promote a trained model to production. The trained model seems to be in a good state in the development environment. The model was trained using the api version 2022-08-31

Running a operation call and getdocumentmodel, indicates that the custom model has been created successfully with a status "Succeeded" as highlighted below.

GeOperation

GetDocumentModel

Where the issue starts is when making the calls to destination DocumentModelAdministrationClient, the GetCopyAuthorization works fine, returning the "DocumentModelCopyAuthorization" as expected. When making a call to the CopyDocumentModelTo, I am getting an error "ModelNotReady"

When I return the GetCopyAuthorization after the first call fails, I get an error that the "ModelExists". This happens despite the "target" models document client GetDocumentModels doesn't return the model in question. Below is the error I am getting on the copy authorization:

Hi @YutongTie-MSFT so it turns out this is a non issue. There was actually a bug on my code. I was attempting to run the "CopyDocumentModelTo" against the target client instead of the source client.

My code looked like this:

var targetAuthorizationCopy = _targetModelClient.GetCopyAuthorization(sourceModel.ModelId);
                    var copyModelToTarget = 
_targetModelClient.CopyDocumentModelTo(Azure.WaitUntil.Completed, sourceModel.ModelId, targetAuthorizationCopy);

It is actually meant to look like this:

var targetAuthorizationCopy = _targetModelClient.GetCopyAuthorization(sourceModel.ModelId);
                    var copyModelToTarget = _sourceModelClient.CopyDocumentModelTo(Azure.WaitUntil.Completed, sourceModel.ModelId, targetAuthorizationCopy);
