I have create a Trigger in my App Center app. This trigger is able to be dragged onto a Journey as an Entry Event.
The trigger is properly calling my endpoints to get its configure.json (which provides its icons, etc.) and index.html, as documented here: https://developer.salesforce.com/docs/atlas.en-us.mc-app-development.meta/mc-app-development/example-contact-decision-event.htm .
I am able to save the Journey, but I AM NOT able to Activate the Journey. I receive an Error with no other description or details. I have verified in Google dev tools Network Sources that the Error array is indeed empty so there is no getting any details there. I have been able to Activate the Journey using a different Entry source, so I am near certain there is some configuration issue missing, but the question is what?
Any further troubleshooting assistance or similar is greatly appreciated.
Thanks so much!
