How do you determine if a property exists or not in a JSON object with Power Automate Desktop?
I am using Set Variable to get the value of a JSON object property. Sometimes this property isn't present, however, and the desktop flow stops with an error. I tried wrapping the Set Variable action in an "On block error", with the "Continue flow run" option set (screenshot below), and then checking for empty string afterward. The "On block error" doesn't work, however, and the Set Variable action's error stops the desktop flow.
I've tried a few other things, but none have worked so far. Is it possible to determine if a property exists or not in a JSON object with Power Automate Desktop?
