Initially, I couldn’t create a client-level role using keycloak-admin-client. I decided to try to do this via the API using Postman in order to make sure that it doesn’t work out that way either.

I think I’m sending the request correctly. The authorization token in the headers and the json representation of the role in the body.

I claim that the client exists, the user I use has administrator rights.

In my java project, it looks like this:

    public int createClient(String clientId) {
        ClientRepresentation clientRepresentation = new ClientRepresentation();
        clientRepresentation.setClientId(clientId);
        clientRepresentation.setPublicClient(false);
        clientRepresentation.setEnabled(true);
        clientRepresentation.setServiceAccountsEnabled(true);

        Response response = clientsManager.create(clientRepresentation);
        int statusCode = response.getStatus();
        log.info("HTTP Status of client creation = {}", statusCode);

        if (statusCode == 201) fillClientWithRoles(clientId);
        return statusCode;
    }

    public void fillClientWithRoles(String clientId) {
        ClientResource clientResource = clientsManager.get(clientId);
        log.info("client: {}", clientResource);
        for (ClientRole role : ClientRole.values()) {
            RoleRepresentation roleRepresentation = new RoleRepresentation();
            roleRepresentation.setName(role.name());
            roleRepresentation.setClientRole(true);
            roleRepresentation.setComposite(false);

            clientResource.roles().create(roleRepresentation);
        }
    }

The Keycloak object is configured correctly. I can, for example, successfully create new users

I reread a bunch of articles, turned to bots for advice, but I still haven’t found a solution that would explain the cause of the 404 error in this request and help solve the problem
