Issue Description

When setting the Parse Server option directAccess: true, the request object in triggers have no IP address set.

This could be considered a characteristic of the direct access feature, but there are a few test cases that expect the IP address to be set, so it should probably be considered a bug.

parse-server/spec/CloudCode.spec.js

Lines 2006 to 2015 in 4b3ce20

	describe('cloud functions', () => {
	it('Should have request ip', done => {
	Parse.Cloud.define('myFunction', req => {
	expect(req.ip).toBeDefined();
	return 'success';
	});
	Parse.Cloud.run('myFunction', {}).then(() => done());
	});
	});

parse-server/spec/CloudCode.spec.js

Lines 2083 to 2091 in 4b3ce20

	it('should have request ip', done => {
	Parse.Cloud.afterSave('MyObject', req => {
	expect(req.ip).toBeDefined();
	});
	const MyObject = Parse.Object.extend('MyObject');
	const myObject = new MyObject();
	myObject.save().then(() => done());
	});

parse-server/spec/CloudCode.spec.js

Lines 2468 to 2483 in 4b3ce20

	it('should have request ip', done => {
	Parse.Cloud.beforeFind('MyObject', req => {
	expect(req.ip).toBeDefined();
	});
	const MyObject = Parse.Object.extend('MyObject');
	const myObject = new MyObject();
	myObject
	.save()
	.then(myObj => {
	const query = new Parse.Query('MyObject');
	query.equalTo('objectId', myObj.id);
	return Promise.all([query.get(myObj.id), query.first(), query.find()]);
	})
	.then(() => done());
	});

All these tests pass, only because the test suite does not actually use the ParseServerRESTController because the test helper always sets the normal REST controller:

parse-server/spec/helper.js

Line 169 in 4b3ce20

Parse.CoreManager.setRESTController(RESTController);

See #8808 for context about this override.

Steps to reproduce

1. Set Parse Server option directAccess: true.
2. Save a Parse.User.
3. The request object in Parse.Cloud.beforeSave('_User', async request => { ... }); has the property request.ip set to undefined.

Actual Outcome

request.ip set to undefined

Expected Outcome

request.ip set to localhost, e.g. 127.0.0.1 in IPv4 environments or ::1 in IPv6 environments.

Possibly just set the IP with a simple:

function getLoopbackAddress() {
  const isIPv6Supported = os.networkInterfaces().lo0?.some(iface => iface.family === 'IPv6');
  return isIPv6Supported ? '::1' : '127.0.0.1';
}

Environment

Server

• Parse Server version: 6.3.1
