            context: 'To give results in your area',
            permissions: 'DEVICE_PRECISE_LOCATION',
        }));
    };

Update to the last version of the package and try this:

const {Permission} = require('actions-on-google');
 ...

const conv = agent.conv(); // Get Actions on Google library conversation object
conv.ask(new Permission({
  context: 'To give results in your area',
  permissions: 'DEVICE_PRECISE_LOCATION',
}));
agent.add(conv); // Add Actions on Google library responses to your agent's response
