PowerApps Flow Button returns "Failed during http send request" when trying to associate

[Anonymous]

This is currently working in previously built apps but we noticed yesterday we cannot associate a Flow with a button in PowerApps currently. I've built a test app simply with one button on the screen and created a simple Flow using PowerApps as the trigger and Send an email (V2) as the action. When tested in Flow it works correctly. It will NOT attach to the button in PowerApps though. The error it returns is "Failed during http send request". We have also tried other actions besides email in the test Flow and it still fails and fails for every user we've tested.

We have tried multiple Flows and multiple avenues to attach the Flow to the button and it fails every time. I've included screenshots to show the error. 

Please help!!

Any updates on this issue?

I am getting the same error when trying to create a flow that adds an item to a SharePoint list.

I get the same results (inconsistently) when using the SQL Execute a Stored Procedure action to return a Request.Response. Works in Flow/Power Automate just fine.

Save a copy of another workflow and then attach

I just realized that this issue has to be, at least in my case, with the response component. When you say to the component to generate the JSON Schema automatically, it creates a part  "required":[.........]. If you erase that part the problem dissapear.

@majuarezg Thank you for the tip - it solved it on my end as well! I actually wondered about that extra part that was added to the schema when inputting a sample of the result output for Flow to automatically determine the schema and even wondered to delete it from the beginning (but sadly didn't).
