PR Checklist
What is the current behavior?
Server function calls only reject when the response carries an
X-Errorheader. Two cases slip past that check inpackages/start/src/fns/client.ts:X-Error, so the promise resolves and callers mistake server failure for success.undefined, so callers have no error to inspect or match on.Minimal reproduction: https://github.com/adipascu/solid-start-server-fn-500-repro
What is the new behavior?
Responses with status >= 500 throw the deserialized result the same way
X-Errordoes, falling back to anErrorcarrying the status when the body yields nothing. 4xx responses are untouched, since server functions can legitimately return them withoutX-Error.Other information
This is the follow-up to #2159, which was merged onto
1.xwhere I asked whether to retarget it atmain. v2's rewritten client has the same logic, so the same fix applies.Added
packages/start/src/fns/client.spec.tsbeside the existinghandler.spec.ts. Both regression tests were confirmed to fail without the source change.
