Hello, I am not sure whats ging on with the issue. But I think if you have the source code, you could debug it in livve so you will find the line which causes the error. You could be correct when you said it is not he credential issue, but we will know whats going using the debugging method. I am able to debug on you desktop remotely, so you dont need to share the source code and we could keep it on your desktop safely. Anyway, the Sharepoint platform is Sharepoint for Desktop or Shrepoint Online? And what Sharepoint version do you have?
