Well this is unfortunate: it looks like GHC might be too big [1] for
Phabricator's HTTP git hosting logic. Unfortunately it's hard to claim
this with much confidence since the endpoint provides no error message
beyond a 500 status code.

I'm not really sure what to advise here; I'll try to raise a flag with
the Phacility people but even if I could confirm that T4369 is the
culprit, it's a bug that still unfixed after more than two years and I
don't hold out much hope that there will be a fix in the near-term. They
suggest that affected users instead use SSH. Sadly this would mean that
you would need to provide a key to your bot.

It is certainly not a very satisfying answer, but I'm afraid it is
likely the best we'll be able to do for a while.
