Error POSTing to endpoint (HTTP 400): jsonrpc: 2.0, error: code 3200, Session not found or expired

Since some time in 0.4.x. I've been consistently getting this message if I left an OpenCode session running for ~10mins+ (roughly, can't remember exactly how long)

It wasn't an issue before that at all and I'm not doing anything special, happens across multiple different tabs in Ghostty

Running on Macbook Pro M4 Max

Current OpenCode version v0.5.7

MacOS Sequoia 15.6

Not sure what other info I can supply to try to pinpoint this

This issue might be a duplicate of existing issues. Please check:

failed to send message: POST "http://127.0.0.1:53737/session/ses_7fcdb17a2ffeA A8MIzJJs741C/message": 400 Bad Request {"name":"UnknownError","data":{"message":"TypeErro r: undefined is not an object (evaluating 'U0.tokens.input')"}} #942: Similar POST endpoint error with HTTP 400 and session-related failure pattern

Feel free to ignore if none of these address your specific case.
