Openshift 3 cluster installation issue – CentOS

I am installing Openshift 3.11 version cluster on my Centos 7.8 VMS. The configuration is that there are three Centos VMs (one master node + two worker nodes). I have configured my inventory file also and ‘prerequisites.yml’ playbook also ran successfully. But when I am running the playbook ‘deploy_cluster.yml’, then it is generating errors as follows —-

[WARNING]: Module invocation had junk after the JSON data: Error in atexit._run_exitfuncs: Traceback (most recent call last):   File
"/usr/lib64/python2.7/atexit.py", line 24, in _run_exitfuncs     func(*targs, **kargs)   File
"/tmp/ansible_oc_obj_payload_A0Bg8i/ansible_oc_obj_payload.zip/ansible/modules/oc_obj.py", line 1257, in cleanup AttributeError:

"/tmp/ansible_oc_obj_payload_A0Bg8i/ansible_oc_obj_payload.zip/ansible/modules/oc_obj.py", line 1257, in cleanup AttributeError:
'NoneType' object has no attribute 'path'

At the end, the installer is failing.

For this, I even checked ‘/var/spool/abrt’ directory but found the same error message —
‘NoneType’ object has no attribute ‘path’

I have also found out the following logs —-

I am not able to figure out what is the issue ? Can anybody help me in this ?
