Satellite 6 inventory sync fails in Ansible Automation Platform with "TypeError: the JSON object must be str, bytes or bytearray, not list" in redhat.satellite foreman plugin

Issue

• Satellite 6 inventory synchronization fails in Automation Controller when the inventory source uses the satellite6 (foreman) plugin and the Reports API.

  [WARNING]: * Failed to parse /runner/inventory/foreman.yml with auto plugin:
  the JSON object must be str, bytes or bytearray, not list
  File ".../redhat/satellite/plugins/inventory/foreman.py", line 438, in _post_request
      self._cache[self.cache_key][url] = json.loads(response.json())
  TypeError: the JSON object must be str, bytes or bytearray, not list
  

• The failure occurs during inventory update jobs that call the Satellite Ansible Inventory report (report_data) path. Inventory sources that do not set use_reports_api: false use this path by default.
