We get the following error (edited slightly):
Dec 19 06:13:27 commit_messages| An error occurred while executing
'/usr/bin/git rev-list --max-count=-1 upstream/master..HEAD':
fatal: ambiguous argument 'upstream/master..HEAD':
unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
We'll need to adjust the remotes to make `upstream` mean what we expect.
This directory contains scripts that are used in building, managing,
testing, and other forms of work in a Zulip development environment.
Note that tools that are also useful in production belong in
scripts/ or should be Django management commands.
