I have built a Power Automate custom connector with a webhook trigger. The connector works with Microsoft's Graph API to retrieve and alter data, and I'm attempting to use webhooks with the Graph API to trigger actions. When I test the trigger in a simple flow I've created, the output shows the following message:
"Validation: Testing client application reachability for subscription Request-Id:" followed by a GUID which varies. I can't seem to figure out what this message means.
The connector does not seem to get triggered by the intended action, and it only seems to perform its action on an hourly basis, and always returns the above message.
Does anyone have any advice on how to further debug this issue?
