Keycloak. Could not find client when trying to create a client-level role

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.enter image description hereenter image description here

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
