Custom oAuth2 stopped working

[markuswinkler]

Issue Description

I have a custom oAuth2 configuration for linkedIn that worked fine until recently.
The oAuth2 redirect url doesn't get handled anymore.
Anyone else ran into that problem?

Expected Results

redirect to the custom oAuth2 handler

Actual Outcome

displays "Cannot get /oauth/linkedin"

Environment Setup

config file:

const api = new ParseServer({
	databaseURI: databaseUri,
	databaseOptions: {
		poolSize: 10,
		reconnectTries: 15,
		socketOptions: {keepAlive: 1, connectTimeoutMS: 30000},
		auto_reconnect: true
	},
	cloud: process.env.CLOUD_CODE_MAIN || __dirname + "/cloud/main.js",
	appId: process.env.APP_ID,
	masterKey: process.env.MASTER_KEY,
	serverURL: process.env.SERVER_URL,
	enableAnonymousUsers: false,
	allowClientClassCreation: false,
	facebookAppIds: process.env.PARSE_SERVER_FACEBOOK_APP_IDS,
	auth: {
		facebook: {
			appIds: [process.env.PARSE_SERVER_FACEBOOK_APP_IDS ]
		},
		linkedin_crypt: {
			module: "../../../../cloud/linkedin_encrypt.js"
		}
	},
	push: {
		adapter: oneSignalPushAdapter
	}
});

Parse server doesn’t handle oauth redirection for you, so have a look into the LinkedIn documentation, they may have changed something there.

Found what caused it. iOS >= 11.2 breaks Universal Links. 😡
Work around was to use a UIWebView with a local url scheme instead of SFSafariViewController.
Thought I post this here in case anybody else runs into this issue.
