Changelog Entry

Description

This pull request fixes a bug that blocks image generation.
The error happens since url is represented as tuple instead of string

Fixed

Fixed a connection error while generating an image

Additional Information and Screenshots

Test plan

Start a new chat
Enable image integration
Submit "Photo of a blue cat" message

Context:
I am running openwebui using ghcr.io/open-webui/open-webui:v0.6.38 docker contaner

My images settings

Before:
Getting "An error occurred while generating an image" when trying to generate an image.

I can find this error in DEBUG logs

Image generation was attempted but failed. The system is currently unable to generate the image. Tell the user that an error occurred: [ERROR: No connection adapters were found for "(\'https://api.imagerouter.io/v1/openai/images/generations\',)"]

which comes from backend\open_webui\utils\middleware.py:931

It happens since url in backend\open_webui\routers\images.py:552 is a tuple, not a string

After:

Image generation works as expected
