In this scenario, if you immediately (without restarting Emacs/reloading
anything) re-run M-x excorporate does it still fail? I just want to
make sure that's not a transient failure. If it does fail the second
time, can you post the HTTP response from the server?

OK.

Are you in a position to build Emacs master tip and retry the experiment
without patching anything?
