Jenkins docker load permission denied

I am trying to load a tar ball using docker load in Jenkins pipeline. I am getting below error

+ docker load -i /home/test/build_artifacts/test.tar
open /home/test/build_artifacts/test.tar: permission denied

Here is my docker pipeline script

docker.withRegistry(registry, credentials) {
      sh "docker load -i /home/test/build_artifacts/${repo_name}.tar"
      docker.image(repo_name).push('latest')
}

I have already tried below and restarted my jenkins!

sudo usermod -a -G docker jenkins

and

sudo usermod -a -G docker root

Further docker load on terminal runs perfectly fine, so it must something related to jenkins

    The solution lies in the fact that docker save always creates a tarball with restricted permissions, we need to do a chmod 755 immediately after saving the file in the source machine then docker load in the destination works perfectly!

    When you use terminal, you are authenticated as your local user who probably has the necessary permissions. When you run a Jenkins pipeline, the pipeline runs as the jenkins user who is likely missing the necessary permissions. You either need to use chmod to give the permissions, or have the artifacts get created and retrieved from within the jenkins users’ home directory.
