      keyFile: <service account json key path>,
      scopes: [
        'https://www.googleapis.com/auth/business.manage',
        'https://www.googleapis.com/auth/plus.business.manage',
      ],
    });
    const client = await auth.getClient();
     const url =
        'https://mybusinessaccountmanagement.googleapis.com/v1/accounts';
      const res = await client.request({ url });
      console.log(res.data);

i want to fetch all my business locations and their reviews. Please help

How exactly are you expecting a service account to have access to GBP resources like location groups, locations and reviews? In order to have access to them, a Google account (i.e. a Workspace account or a private Gmail account) needs to exist and have manager or owner permissions.

For requesting the data that you seek, you need to authenticate using that Google account.
