I am getting the same problem in the sandbox app
I did replace the “YOUR_API_KEY”, I tried replacing manually, also the UI replaces it automatically (there is even a comment at the top of the code snippet in the UI saying they did it for me)
I tried regenerating the api key and replacing again
recreating the app
recreating the grant
nothing worked, any clues?
EDIT: It worked when I recreated the app with USA data residency, this isn’t good for me because I work in Europe, you should probably check this out
