Discovery error message 'Script error in sensor: ReferenceError: "related_data" is not defined.' Issue  Symptoms Discovery is showing an error: error - 'Script error in sensor: ReferenceError: "related_data" is not defined.'

Steps to Reproduce:

Run Discovery on a Windows Desktop Machine. The Windows- Installed Software probe throws the error Release London

Cause There have been several code changes over the years.

The " Windows - Installed Software " sensor now calls this.prepareJSON(result) to extract the discovered payload and set variables which include a variable named " related_data ". The prepareJSON() function is implemented in parent Script Include " DiscoverySensor " You might have customized DiscoverySensor script includes which prevented from getting upgraded. The older DiscoverySensor script include does not have the prepareJSON() function so no variable named " related_data " is initialized, leading to the error. Resolution Revert the DiscoveySensor script include out of box version.
