Execution failure in 'chat_with_context': TypeError for unsupported operand 'NoneType' and 'NoneType' in Azure AI Studio Chatbot Deployment

Hun Hui 25

I have developed and deployed a chatbot using Azure AI Studio, but I encountered the following error during execution:

Error Message:

Execution failure in 'chat_with_context': (TypeError) unsupported operand type(s) for +: 'NoneType' and 'NoneType'

This error seems to occur when the chatbot attempts to process or concatenate NoneType values during the 'chat_with_context' phase. The error indicates that two NoneType values are being used with the + operator, which is causing a TypeError.

I am looking for guidance on how to troubleshoot and resolve this issue, and would appreciate any suggestions on how to handle NoneType values or avoid this error during deployment.

@Hun Hui Was this an error that occurred recently after your chatbot was first setup successfully? Which model did you use to deploy as an endpoint and use with chat?

With respect to standard OpenAI models which are deployed as endpoints, I do not think there is an option to lookup the logs of these models, if you have used any model from model catalog then the deployment will display logs when you click on the deployment or endpoint name.

If the error is from webapp deployment then you might have to lookup the webapp logs at the resource level in azure portal to check if there are more details to debug.

If all above options are already checked, please raise a support case from azure portal so that the support team can further take a look at this issue. Thanks!!

Any updates on the issue? This seems to be also related and I'm having same problem.

@Hun Hui Posting the solution from the other thread referenced.

Please try the workaround to disable tracing and redeploy the flow by setting the env var "PF_DISABLE_TRACING" to true, this can avoid the potential error at this time.

It was working well with this code below on "flow.dag.yml"

Thanks!

environment_variables: PF_DISABLE_TRACING: true
