Request entity too large error
Description
Recently hitting a 'request entity too large' response when using any model via Copilot. I haven't hit my usage limits (edu subscription) and the codebase is quite small. Sometimes happens when introducing screenshots, but even after removing these the issue persists. Often requires multiple session restarts or reworking from scratch.
OpenCode version
1.0.218
Steps to reproduce
No response
Screenshot and/or share link
Operating System
MacOS 26.2
Terminal
Ghostty
+1 I am also facing this, since this evening.
It surfaced on a session with many screenshots, on a project without screenshots i did not hit this today, yet.
Same thing just happened to me.
Didn't think it was a copilot thing. @Clock-Drift
Same here with claude-sonnet-4.
It happens with a big Playwright Testing Suite and several screenshots.
It has stopped for me. I think Copilot is having issues, or this is just their rate limiting.
Some models disappeared recently from my Copilot account, only to come back this morning. I'm not sure what's going on at Microsoft/GitHub.
It happens to me too on v1.1.12. Reproducible with multiple Copilot models after accumulating a few images in the conversation.
seems these issues might soon be a thing of the past as copilot auth will be official per this post!
I'm on v1.1.21. Still having this issue
Using co-pilot and Claude 4.5 Opus
