There was a problem hiding this comment.
I don't think this should be just for body Timeout errors - we can have a request ID for all TFY gateway requests, and log in all gateway errors.

Low Risk
Observability and an extra outbound header on model calls; error handling behavior is unchanged aside from richer Body Timeout logs.
Overview
Adds request correlation for undici Body Timeout failures on Vercel AI SDK model calls.
Each streaming
VercelAILLM.createcall now setsx-tfy-request-id(new UUID) on outbound provider headers. When a Body Timeout is detected (including nested underfetch failed), logging uses a dedicatedLLM Body Timeoutpath withtfy_request_id, model, and optionalgateway_urlinstead of the generic stream/create error messages—so harness logs can be tied to AI Gateway traces.Exports
