Grafana OAUTH not request token_url

my config in ini file:

[auth.generic_oauth]

enabled = true

allow_sign_up = true

name = OAuth

client_id = mangatoon

client_secret = a02e23f8d2f96078c7afc42895a77e2c

scopes = openid email name

auth_url = url1
token_url = url2
api_url = url3

when i sign in with OAuth , Grafana web redirect to the auth_url . I get the request_uri and state in request params and redirect to the request_uri with state and code. but Grafana server never request token_url and api_url . How can i resolve it ?
