 I am trying to authenticate with my keycloak instance using the following credentials but am met with the `error=invalid_client_credentials` in the console. 

```

```auto
 const kcAdminClient = new KcAdminClient({
            baseUrl: process.env.KEYCLOAK_URL,
            realmName: process.env.KEYCLOAK_REALM,
          });
      await kcAdminClient.auth({
        username: "realm-root",
        password: "rolemodel",
        grantType: "password",
        clientId: "cycube",
      });

```

The following is my config in the ui

I have spent the past day trying to figure it out but am totally clueless about what I am doing wrong. Any help is appreciated.

Your client is `Acess Type: confidential` but your code is not sending any client secret, so `invalid_client_credentials` is valid error for this case. Make sure your client is `public`, not `confidential`.
