Assistant environment expires, but doesn't in playground

After ~1 hour of inactivity, the assistant’s environment expires and is unable to see which files are tied to the assistant.

I receive a message like the following:

Currently, I don’t have access to any files because the code execution environment was reset, which cleared any previously uploaded files. Please re-upload any files you need assistance with, and I’ll be happy to help.

But when I open the same assistant within the playground, it doesn’t have this issue and it able to retrieve information from the files associated.

Any guidance here?

Thanks in advance,

David

I have exactly the same error.
Does the session have a timeout or something ?
