Is there a way to get more error details for canvas? Trying to test out canvas and I get an error "Something went wrong while trying to set up that card, please try again"

All i did was configrue the url, which returns the json from https://developers.intercom.com/canvas-kit-reference/reference/canvas and I'm stuck on the first step.....

I used chrome console and I see that the error_code is third_party_malformed_response_error

Here is the URL I'm using for the initialize step -
