Additional Information
I checked the payment at open ai plattform and i can see it was paid, so the setup itself to connect to open ai worked without issues.
tested with dall-e-2 and dall-e-3
@adambrakhane commented on GitHub (May 6, 2025):
I'm seeing this too. Looks to be a regression where the Authorization header is being sent w/ the request errornously. Azure sees both methods & defaults to the header key (which fails). Headers need to be excluded from the request to get the image.
@tjbck commented on GitHub (May 6, 2025):
Is this also the case in dev? could anyone confirm?
@0xGitGuy commented on GitHub (May 12, 2025):
I'm also having this problem. Was this included in the latest v0.6.9?

@haudamekki commented on GitHub (May 13, 2025):
I have the same Problem with Version 0.6.9
@johnygke commented on GitHub (Jun 30, 2025):
has anyone found a way to resolve this issue? My workflow can't complete.
@johnwjm commented on GitHub (Nov 16, 2025):
I ended up reverting back to 0.6.33. Nothing I tried worked on the later releases.
@tolidano commented on GitHub (Jan 18, 2026):
This was (apparently) working and now it's not working anymore. https://www.reddit.com/r/OpenWebUI/comments/1oy60jr/image_generation_issues/
@Classic298 commented on GitHub (Jan 18, 2026):
@tolidano not working for you? share your setup. working fine for me
