When i try to connect using keycloak-admin-client it gives me Invalid client or Invalid client credentials error. I was able to get the tocken from postman.  
This is my code:

const keycloakAdminClient = require(‘keycloak-admin-client’);  
const keycloakConfig = require(‘…/config/keycloakConfig’);

let keycloakAdminClientInstance;

async function initializeKeycloakAdminClient() {  
try {  
const settings = {  
baseUrl: keycloakConfig.baseUrl,  
realmName: keycloakConfig.realmName,  
clientId: keycloakConfig.clientId,  
clientSecret: keycloakConfig.clientSecret,  
grant\_type: ‘client\_credentials’,  
};  
keycloakAdminClientInstance = await keycloakAdminClient(settings);

```
    console.log('Keycloak Admin Client initialized successfully');
} catch (error) {
    console.error('Keycloak Admin Client initialization failed:', error);
    throw error;
}

```

}
