git diff throws an error "fatal: ambiguous argument"

[flacial]

Issue on Sentry

The CLI attempted to run git diff master..js0/5 and it threw:

Error: fatal: ambiguous argument 'master..js0/5': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
