How to get BITBUCKET_BRANCH in a step within tags?

Question

I have a tag defined as following. And I want to retrieve the BRANCH name from where this pipeline is triggered. As per the documentation, the $BITBUCKET_BRANCH variable is only available for branches.

I need to get BRANCH name for the step "Send Slack". Any suggestion would be appreciated.

tags:
'dev/trigger':
    - step:
name: Deploying to Dev
deployment: dev
script:
          - git branch
          - pipe: docker://<pipe_name>
variables:
NAMESPACE: $NAMESPACE
BUILD_HELM: $BUILD_HELM                  
    - step:        
name: Send Slack
script:
          - declare -x VERSION=$(cat version.txt)          
          - pipe: atlassian/slack-notify:0.3.2
variables:
WEBHOOK_URL: $SLACK_URL
MESSAGE: "Deployed from Pipeline to env:DEV  project:${PROJECT}  version:${VERSION} "

thanks for the hint with:

clone: 
 depth: full

it solved the problem for me too.

BTW: "git checkout" is not required for "git branch --contains"
For me it worked to use:

git branch -a --contains tags/${BITBUCKET_TAG}

or

git branch -r --contains tags/${BITBUCKET_TAG}

because there are no local branches the -r (remote branches) or -a (all branches) helps

For me, the fix was a very special/secret incantation of both the following in a step (like this)

clone: 
 depth: full

And then in the "script"

- git checkout master

This was to ensure that I can run the following just to validate that a tag was in the master branch.

- export TAG_INFO=`git branch --contains tags/$BITBUCKET_TAG 2>/dev/null`

And wow... that was painful! Looking back I pushed 18 tags over an hour or so just to figure it out.

Did you ever figure this out?

I'm getting the same exact result and I'm having a hard time trying to figure out how to restrict tags like `0.0.0` to only be on `master` 😓
