Unable to access Git Tags

I’m trying to fork some logic based on git tags. Unfortunately I am unable to access them. Here’s what I’m doing:

WA02C53FD56:Someproject timothy_dalbey$ git add --all && git commit -m “Testing tag parsing” && git tag “$RANDOM” && git tag “$RANDOM” && git push origin master
[master 66677a6] Testing tag parsing

WA02C53FD56:Someproject timothy_dalbey$ git tag --points-at 66677a615327d03d6e8e5b223682a5875da1b369

But in Circle the following does not work:

echo "$CIRCLE_TAG";

and neither does

git tag --points-at $CIRCLE_SHA1

However, I am able to get commit messages via

git log --format=oneline -n 1 $CIRCLE_SHA1

Based on comments I’ve come across from the interwebs, I’ve also added the following to the dependencies section of the circle.yml, to no result:

- git fetch --tags
