 * Hello, I am using JWT Authentication for WP REST API to authenticate from my 
   Android app but when I try to login I receive this response: “Response (HttpMethod.
   POST): 403 {“code”:”jwt_auth_bad_auth_header”,”message”:”Authorization header
   malformed.”,”data”:{“status”:403}}”
 * How can I fix this?
