Good Day @MatthewAttiyeh1 ,
I was able to recreate the issue you were experiencing and I think I found a solution - it took a couple of steps, but I have gotten the web hooks to fire on submission of a request in the Citizen Problem Reporter Solution.
The feature layer that worked and fired the webhook was the 'Requests_reporter' which is a Feature Layer (hosted, view).
The red arrow is pointing to the feature layer view that is edited when a request is submitted through the Citizen Problem Reporter solution.
The next step was to confirm the 'Editing' settings are correct. For Power Automate to catch the web hooks, the 'Keep track of changes to the data (add, update, delete features)' must be selected. Initially it was not checked in the initial deploy of the Citizen Problem Reporter solution.
Make sure the 'Keep track of changes' check box is selected.
The next step was pointing to the Power Automate Trigger to the appropriate feature layer, which was 'Requests_reporter / undefined' and using the 'Fetch updates, changes, or deletions from feature layer' action to get the payload back from the web hook.
Hopefully this helps, if it doesn't please let me know and we can continue to troubleshoot the issue.
