Hi,
Today 3 members of our ~6 person dev team started seeing this exception when running any arcanist command that interacted with the phabricator service:
```

Data is normally attached by calling the corresponding needX() method on the Query class when the object is loaded. You can also call the corresponding attachX() method explicitly. at [<phutil>/src/conduit/ConduitFuture.php:58]

We were running a ~week old release of phabricator, then upgraded to master (ie b34d5bf44ba96b7b11d7a72e1056a979406b3e93), and all of us ran `arc upgrade`. The problem persisted until someone made this hacky patch, which fixed the problem:
```
ubuntu@work:/var/app/phabricator$ git diff
diff --git a/src/applications/people/conduit/UserConduitAPIMethod.php b/src/applications/people/conduit/UserConduitAPIMethod.php

if ($until) {
$return['currentStatus'] = 'away';
$return['currentStatusUntil'] = $until;
}

return $return;
}
```
If it's any help, here's my arc version post-upgrade (which wasn't working before we made the patch):
```
➜ ~ arc --version
arcanist c6fa42b9c5c07f79d4b76f91b0378b9d9ffa7a00 (14 May 2015)
libphutil dc4b8571f97515f30eed334f94142f7d1f761674 (14 May 2015)
```
After making the patch, all functionality has resumed working properly.
Best,
Pavel
