### Issue details

I've been using the Azure.ResourceManager.DataFactory SDK and recently encountered an issue. Previously, I used the GetDataFactoryPipeline method to retrieve my pipeline details and then run it in the next step. This setup has been working fine. However, yesterday, when I tried to run the pipeline, it threw an exception from the GetDataFactoryPipeline method.

The stack trace is:
---------------------------------------------------------------------------------
System.InvalidCastException
HResult=0x80004002
Message=Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'System.String'.

Above stack track trace states that something strange is released and the object is changed from System.String to System.Collections.Generic.Dictionary`2[System.String,System.Object].

I did not see any parameter changes for the same function (GetDataFactoryPipeline), I believe this is an internal issue and want this issue to address ASAP.
