Laravel 5.4 Dingo/JWT API: Failed to authenticate for valid token

Question

I've implemented Dingo REST API with Laravel 5.4. I'm able to fetch the token from the server. As well as the toke is successfully received by the server. But it is throwing 401 exception and this is the debug stack trace:

I've already tried to pass the token through url same results.

I finally resolved this issue long back. Actually while making request to Dingo API with Volley. We have to set the Content Type header to JSON.

Hope it helps someone.
