In the middle of qwen working hard (4w84-gck0-pn4g-fa9e):

error: failed to continue conversation: error, status code: 502, status: 502 Bad Gateway, message: invalid character 'o' looking for beginning of value, body: oai proxy error: http2: Transport: cannot retry err [stream error: stream ID 77; PROTOCOL_ERROR; received from peer] after Request.Body was written; define Request.GetBody to avoid this error

A continue kept the session going.

I tink this fireworks.ai being flaky. Not clear there's anything we can do here.
