Concourse - Pipeline returns "Detecting the current branch failed: fatal: ref HEAD is not a symbolic ref"

Question

I am running a maven release plugin in concourse pipeline. Our Git is in GitHub Enterprise and so is our Artifactory.

I am getting the resource, I am able to build it and release a snapshot to Artifactory using deploy. But when I go for the release concourse fails with ref HEAD is not a symbolic ref

Here is my CI code that does the release:

- name: build-release
  plan:
  - get: tool-v2
    params: {depth: 1}
    #passed: [ build-docker-image ]
  - task: build
    config:
      platform: linux
      image_resource:
        type: docker-image
        source:
          repository: adoptopenjdk/openjdk11
          tag: "latest"
      inputs:
      - name: tool-v2
      outputs:
      - name: built-artifact-release
      run:
        path: /bin/bash
        args:
          - -c
          - |
            set -e
            apt-get update && apt-get install -y git
            cd tool-v2
            git config --global user.email "emailadd"
            git config --global user.name "Service Account"
            ./mvnw release:clean release:prepare -B
            ./mvnw release:perform -B -Darguments="-Dmaven.javadoc.skip=true -DscmCommentPrefix='[skip ci]'"
            ./git push --tags origin main:release

Here is the error I am getting in the pipeline:

I tried all the available options. I tried adding depth from 1 to 100 still the same error. I added version: ref: commit-sha and the error still remains.
