gluster-kubernetes Error waiting for job 'heketi-storage-copy-job' to complete

As the title says, while using the gk-deploy script, it ends in failure with the following error: Error waiting for job 'heketi-storage-copy-job' to complete.

Here's the command: ./gk-deploy -g ../../storage_topology.json --admin-key admin --user-key user

And here's the output:

I used the get event command to find out the errors: kubectl get ev --field-selector involvedObject.name=heketi-storage-copy-job-hbvv4

And the output was:
