"Unhandled exception: name '__file__' is not defined"

[EtiennePerot]

Open WebUI commit open-webui/open-webui@cf86ba7 breaks this tool due to tools and functions no longer being written to files on disk. The tool and function re-execute themselves as subprocesses in order to function, by using Python's special __file__ global variable which is normally defined for modules when they are imported.

This manifests in Open WebUI as an error saying: Unhandled exception: name '__file__' is not defined.

Facing same issue.

Sorry about that. The fix needs to happen in Open WebUI first, not this tool. I have a fix for Open WebUI at EtiennePerot/open-webui@6477bf3 which I will send as a PR tomorrow and hope they accept it.

In the meantime, as a workaround, you can use an older version of Open WebUI; basically any version older than open-webui/open-webui@cf86ba7. For example, if you are using the Open WebUI container image, I've verified that ghcr.io/open-webui/open-webui:git-27109d2 is old enough to not have this problem.

A PR to fix this was sent to Open WebUI here: open-webui/open-webui#5511

This was merged and available in Open WebUI v0.3.22. However the tool has not been updated to work with it yet. Will post here when the fix is released.

This issue is fixed as of release 0.6.0. It will work with Open WebUI v0.3.22, but is also backwards compatible to work with previous Open WebUI versions as well.
