Partial backport of #3469 (agent side only) to b0.72 (#3492)

Replace `requests.exceptions.JSONDecodeError' by generic `Exception'.

See #3469 for some details. The upstream issue is

   psf/requests#5794

and the PR is

   psf/requests#5856

but we are running older versions of `requests' in various places.
