Is it reproducible?  (You can run “make check TESTS=tests/publish.scm”.)

If it is, could you add ‘pk’ calls here and there to see which of the
sub-expressions in (and …) returns false?

For example, replace:

  (= 404 (response-code response)

by:

  (pk 'four-oh-four (= 404 (response-code response)))

That’ll print a line in the test log with the value of that (= …)
expression.

TIA,
Ludo’.
