Hi, I have a flow written that connects to a website that I manage via HTTP and a specific page I built for this purpose. I've written that page to either output the data in XML or plaintext. The flow then takes the data and publishes it to facebook and twitter. I want the flow to check the output before it publishes, and if it contains a certain phrase, then cancel the flow.
The flow works fine without this check. Based on some forum posts I found, I added a "compose" step to grab the output of the HTTP Step. I've tried numorous tests but always end up with "ActionFailed. An action failed. No dependent actions succeeded."

Bsasically I just want the flow to evaluate if "[[DO NOT PUBLISH]]" in the the HTTP output. I've tried the obvious of if the Output of Compose "does not contain" '[[DO NOT PUBLISH]]' but I get the error above.
What is the right way to test for this condition?
