Errors

If an error occurs, all listener events contain up to three keys with the error information.

Key	Description
error	An string based error code.
message	A human readable error message.
status	The numerical status code returned from the network request.

Note

The message and status keys can possibly be nil.

Example Listener

local function onResponse( evt )
  if evt.error then
    print(evt.error, evt.message, evt.status)
  else
    --no errors
  end
end
