        name: 'test',
        rules: [
          {
            alert: 'test_alert',
            expr: 'query',
            annotations: {
              message: 'message',
            },

Sorry, I have realised that this is because to sync alert rules, one needs to have the mimir related environment variables set. I wish the error message was more useful.
