Q: Failed File Uploads

When I tried to upload a .png file, I received this error message:
"Send failed
Declared type 'image/png' for 'CV Shot 2026.png' does not match file contents."

Is this a known issue? Also, when this upload error occurs, the prompt I previously wrote gets cleared from the text box. Would it be possible to have the prompt saved so that users don’t have to rewrite everything when trying to upload another file?

Also, when will we get a feature request/bug fix board?

Thanks for your help!

A: Hello There,

Thanks for sharing this. This is an issue when image headers and extension do not agree with each other - image is actually a PNG but extension is JPEG.

For any support need - please send email to [email protected] - quickest way to get response.

For feature request/bug fix board - we are working on a solution to have this - will try to have an ETA soon

Are you using Openrouter? Mybe you choose there Not a multimodal model?

Nope, I changed the PNG to JPEG, then it worked. That is one thing, but the other is that I lost the big prompt I was writing with it, which was a bit annoying.
