Arc patch fails: EXCEPTION: (ConduitClientException) ERR-INVALID-AUTH: Unknown Error

Hey there,

I've been having trouble running arc patch lately ; asked on Z1336 and got a few hints, but eventually couldn't fixed it. So here we go, maybe someone here will have some more leads :)

Here is all the info I got:

  • I run arc with PHP (cli) in ubuntu 14.04 LTS
  • Both my phabricator and my local arc installs are up to date
  • I can run other arc commands fine (eg. I use arc diff in my daily workflow)
  • Whenever I (or my colleagues who share the same vagrant dev environment) try to arc patch any revision we get the following error:
$ arc patch D217 --trace
 ARGV  '/opt/phacility/arcanist/bin/../scripts/arcanist.php' 'patch' 'D217' '--trace'
 LOAD  Loaded "phutil" from "/opt/phacility/libphutil/src".

  • When I run arc patch and check the webserver logs, conduit response seems fine: xxxxx - - [23/May/2016:09:52:22 +0000] "POST /api/differential.querydiffs HTTP/1.1" 200 5011 "-" "-"
  • I also tested calling conduit directly, response seem fine:
