Any update on this?
I got the exact same message when using POSTMAN :
I fist do this (with grant_type=client_credentials):
http://localhost:8080/auth/realms/sg2b/protocol/openid-connect/token
And then this with the token I received:
GET
http://localhost:8080/auth/realms/sg2b/authz/protection/resource_set?type...
Which answer me this:
{
"error": "invalid_scope",
"error_description": "Requires uma_protection scope."
}
