This is what I did. Result was the second error I pasted above:
FileNotFoundError: [Errno 2] No such file or directory: '/omd/sites/cmk/local/share/check_mk/notifications/sr_servicenow_plugin'
While the file is there. One thing though - when I did a “ls -l” on that path the file had an * after its name. I don’t know what that means.
