Hello,

Currently using Azure AI Foundry Assistants Playground and getting this error:

Failed to update assistant Cannot create property 'tools' on string ''. Trace ID : b772f130-dc8a-43fb-99c3-f96ec0cb5690

How do I fix this? The playground was working perfectly fine yesterday and now this error popped up.

Thanks!

Hello Sav B

Greetings and Welcome to Microsoft Q&A!

I understand that you're encountering this error in the Azure AI Foundry Assistants Playground.

To address this problem, please consider the following steps:

Make sure your assistant's configuration is set up correctly, especially the tools property. It should be defined as an array rather than a string to avoid errors.

Sometimes, clearing the cache of your browser or restarting the Azure AI Foundry session can resolve temporary glitches.

Try restarting your session in the playground, as this can help resolve any temporary issues that may be causing the error.

Make sure your browser is up to date, as compatibility issues can sometimes lead to unexpected errors.

I hope you understand. Do let us know if you have further queries.

Thank you!
