    After various option permutations, I finally was able to inspect a text response with: * Inspect URL content * Monitor a change of the content I couldn't get it to work with any other combination except only and exactly those two. I found the interface very confusing... 1. Checking "[URLTrigger] - Poll with a URL" w/o specifying anything else polls, but never finds any changes. Users should be notified that this is an invalid state, in the config, output, or both 2. [1] and checking "Inspect URL content" causes an error (see [4] below) 3. TXT/"Monitor the contents of a text response" seems especially misleading, since it requires a regex. Not knowing that (although I now see it in the help), I set TXT w/o a regex only to discover later that it was never finding any changes in the context. I think either: - if no regex is supplied, assume all text (.*) - I like this one the best - notify the user that TXT w/o a regex is an invalid config - name it REGEX/"Something mentioning regex" [4] Error output: Error Failed to parse form data.
