Why am I receiving "Failed to parse /runner/inventory/host with script plugin:"?

Issue

• Executing job(s) results in a failed state and returns the following error:

  [WARNING]:  * Failed to parse /runner/inventory/hosts with script plugin:
  problem running /runner/inventory/hosts --list ([Errno 13] Permission denied:
  '/runner/inventory/hosts')
  [WARNING]:  * Failed to parse /runner/inventory/hosts with yaml plugin: We were
  unable to read either as JSON nor YAML, these are the errors we got from each:
  JSON: Expecting value: line 1 column 1 (char 0)  Syntax Error while loading
  YAML.   expected <block end>, but found ','  The error appears to be in
  '/runner/inventory/hosts': line 3, column 40, but may be elsewhere in the file
  depending on the exact syntax problem.  The offending line appears to be:  #
  -*- coding: utf-8 -*- print('{"all": {"hosts": ["localhost"]}, "_meta":
  {"hostvars": {"localhost": {"ansible_connection": "local",
  "ansible_python_interpreter": "{{ ansible_playbook_python }}",
  "remote_tower_enabled": "true", "remote_host_enabled": "true",
  "remote_host_id": 1}}}}')                                        ^ here We
  could be wrong, but this one looks like it might be an issue with missing
  quotes. Always quote template expression brackets when they start a value. For
  instance:      with_items:       - {{ foo }}  Should be written as:
  with_items:       - "{{ foo }}"
