Hey, this is a known bug. The server-side 50 MB request limit gets exceeded when too much context builds up in a chat (message history, skills, rules, large open files). We’re tracking this on our side, but there’s no exact ETA for a fix yet.

Workaround: start a new chat session, which clears the accumulated context. If it happens again quickly, try reducing the number of active skills and rules, and avoid attaching large files to the context in full.

If a new session doesn’t help and the error shows up immediately on the first message, let me know and we’ll take a deeper look.
