JWT Rich Authorization Request - how to set field?

[h0jeZvgoxFepBQ2C]

I'm setting the RAR field like following:

But in my logs it seems that the field is not respected and it can't find any scope?

[debug] Computing username from client's JWT token: [<<"user-a4c90e00-5157-41cb-b024-283cbff80954-1HlDDLn8gY">>] -> user-a4c90e00-5157-41cb-b024-283cbff80954-1HlDDLn8gY
[debug] User 'user-a4c90e00-5157-41cb-b024-283cbff80954-1HlDDLn8gY' authenticated successfully by backend rabbit_auth_backend_oauth2
[debug] Matching virtual host 'vhost1' against the following scopes:
[warning] STOMP login failed for user 'ro_user': virtual host access not allowed
[error] STOMP error frame sent:
[error] Message: "Bad CONNECT"
[error] Detail: "Virtual host 'vhost1' access denied"
[error] Server private detail: none

Any idea what I do wrong?

I found the error, I forgot to set the resource server type:

{resource_server_type, <<"rabbitmq">>}

After adding this in my advanced config file it works.
