fix minor

[hakiiver2]

Thank you for the great example.
When I command create an OAuth client with the command in README, in my environment, the following error appeared, so I made this modification.
I hope this helps.

level=error msg=An error occurred while handling a request audience=application error=map[message:invalid character '}' looking for beginning of object key string stack_trace
