I'm getting the response:
{"support_url":null,"error_code":"third_party_request_error","message":"Something went wrong with the third party server during the request"}
when trying to initialize the app, I don't know what kind of error is involved, no other code error or description is given to know if is a permission issue from my server, when I access the URL set in canvas it returns the following object
{"canvas":{"content":{"components":[{"type":"button","label":"Click Me, This is AppCore!!!!","style":"primary","id":"url_button","action":{"type":"submit"}}]}}}
any help will be appreciated, thanks!
