Both token requests opened HttpResponse.bodyPath with readFileSync, which
ties the plugin to bodies living on a filesystem. The send now hands the body
back, so they read it from there and keep working once bodies move into the
blob DB and in the browser Worker, where there is no fs to read.
text() on a response with no body returns "", which is what the bodyPath
check produced, so an empty response still parses to {} rather than throwing.
