When working with Dialogues, Facebook provide a 'show_error' attribute that defaults to no but can be set to true in a Development environment and is really helpful for debugging purposes.

show_error - If this is set to true, the error code and error description will be displayed in the event of an error.

Instructions of it's use can be found in the Facebook Docs.

I'd been debugging "An Error occurred. Please try later." dialogue before i found this attribute in the docs. Once i started using it, i could see the following message too:

API Error Code: 191

API Error Description: The specified URL is not owned by the application

Error Message: redirect_uri is not owned by the application.
