Does not commit bumped version number in package.json on Bitbucket pipelines

I am having trouble using this in Bitbucket pipeline. It is consistently committing the changelog witout committing the package.json and the bumped version number.(Resulting in the same release version each time). I tried:

• useing barebones configuration to call only standard-version without any flags.
• adding the --commit-all and -a flag
• manually calling git add package.json in precommit and release hook.
• removed all hooks

It works perfectly in local environment, I am not sure what I am missing.

Version: 7.0.0

Release Commit:

Package.json

"scripts": {
    "release": "standard-version --no-verify --prerelease beta"
}, 
...
 "standard-version": {
    "scripts": {
      "postbump": "git add package.json",
      "precommit": "echo \"[skip ci]\""
    },
    "skip": {
      "tag": true
    }
  }
