I have just made some amendments to a Flow. Then when I go to add it in to my App, I get this Failed to register service error.
How do I fix this?
Solved! Go to Solution.
What did you change in your Flow? That may be causing the problem.
Power Apps requires a strict schema for the data that comes back. You need to view the "Response Body JSON Schema" to see if it contains any columns whose data type is null. Each column needs a type.
It is also possible to fail to register if your flow ends with two different responses or schemas.
