Request entity too large error

[Clock-Drift]

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
