Git rev-list --count develop..$CIRCLE_SHA1 returns 0

Build Environment
1

For this repro repo
in a CircleCI pipeline build job
git rev-list --count develop..$CIRCLE_SHA1
returns 0.

Ditto for
git rev-list --count develop..HEAD.

Also git rev-list develop..HEAD does nothing.

All the git commands above produce a different result when run locally.
git rev-list --count HEAD returns the same non zero value for both local and CircleCI runs.
It appears git rev-list fails on CircleCI whenever a gitrevision range argument is supplied
Am I doing something wrong? How do I get git rev-list to work with a gitrevision range?

On CircleCI use the full commit sha1 instead of branch names For example, the sha1 for the develop branch using bash DEVELOP_SHA1=$(git rev-parse origin/develop)

Then LATEST_COMMIT_SINCE_DEVELOP=$(git rev-list -1 develop..$CIRCLE_SHA1) should be written as LATEST_COMMIT_SINCE_DEVELOP=$(git rev-list -1 $DEVELOP_SHA1..$CIRCLE_SHA1)
