I've got this simple transform for dropping unwanted logs which works fine. I went to add something to it and got this Encountered the following error while trying to update: Invalid FORMAT: nullQueue error when I tried to save it. Then I Canceled, and re-clicked on the transform (in Settings>>Fields>>Field transformations) and tried a Save without changing anything and got the same error. Why is that?
REGEX = syslog-conn-status,.*(established|broken)
DEST_KEY = queue
FORMAT = nullQueue
