So I created two simple websites just to test out private click measurement. On one website (hosted on herokuapp) I am showing an advertisement, upon clicking which the user is redirected to another website (hosted on onrender) where the user needs to click a button for the conversion/attribution to happen. Now the first two steps are happening correctly as can be seen from the screenshot below, but I am not getting the attribution report on the POST endpoint /.well-known/private-click-measurement/trigger-attribution/:triggerId, or for that matter any endpoint as I am logging the requests coming to any of the endpoints on the first website. I have followed the PCM documentation for setting up everything. Here is the screenshot of the console log: The different endpoints on the first website:
