I just got this error when trying to update a diff with arc diff:
Exception ERR-CONDUIT-CORE: Argument 1 passed to DifferentialReviewersField::inflateReviewers() must be of the type array, null given, called in /usr/src/phabricator/src/applications/differential/customfield/DifferentialReviewersField.php on line 245 and defined (Run with `--trace` for a full exception trace.)
The diff was no reviewers set, which I'm guessing is the problem.
From the server logs:

This seemed to fix the issue:
