When doing an Endpoint Discover scan, some policies will not trigger that contain a custom DI
A trailing , at the end of the validator in the Custom DI can cause missed detections.
Verify the validators in the custom DI do not contain a trailing , at the end.
For example:
You have a "Exclude beginning character" validator with the text "111,222," or "Exclude prefix" with text "something,something,". In both of these cases remove the trailing , at the end of the text. So in this case you would have "111,222" and "something,something".
