Oauth2 Not Found Any Service! Help!

hello, I'm trying to make requests via the API and I can't properly build the http with the data written in the documentation ... I managed to generate the Refresh Token and authenticate ... then when I make a request trying to execute any method for testing I always get the same mistake.. 

{"error":"not_found","error_description":"Service was not found"}

In bx_oauth_clients i update scope = service to my user....

curl -X POST 'localhost/una/m/oauth2/api/service' \

--header 'content-type: application/x-www-form-urlencoded' \

--header 'Authorization: Bearer 771eadd51a8834815333a5d656ef2025d4522219' \

-d "module=bx_profiler&method=BxBaseServiceProfiles&class=serviceGetProfileTypes"
