I have been working on a prompt flow QnA chatbot for a while now and it has been working well. Recently i redeployed my model with minor changes and the endpoint does not work anymore: below is the error that i have : "Execution failure in 'lookup': (TypeError) unsupported operand type(s) for +: 'NoneType' and 'int' azure". Keep in mind that i haven't changed anything in the "lookup" node, and i couldn't find where the + operand is being done on the flow.

The prompt flow model works well in azure ML studio but deploying somehow makes this error.

Thank you for your help ! It's kind of an urgent matter

    A temporary fix for me was to turn of tracing by setting an env variable: 

    os.environ['PF_DISABLE_TRACING'] = 'true'

    Hi everyone ! I found a fix pour this error : Apparently latest open ai versions cause a problem with prompt flow tracing, so reverting to = < 1.44.1 openai python library in the requirements file fixed the issue for me

    error:

    

The above exception was the direct cause of the following exception:
