Plugin migration from 1.18 to 2.x -> Route.get() requires a callback function but got a [object Undefined]

Plugin Development
  • Hi there,

    I'm trying to migrate my forum to 2.8.2. I have an adapted sso plugin, that adds a GET route to find users by external oauth id.
    The plugin works on 1.18 but breaks on 2.8.x already on startup.

    The error message is:

    2023-01-19T22:37:12.434Z [4567/458] - error: [plugins] Error executing 'static:app.load' in plugin 'nodebb-plugin-sso-oauth-faforever'
    Error: Route.get() requires a callback function but got a [object Undefined]
        at Route.<computed> [as get] (/usr/src/app/node_modules/express/lib/router/route.js:211:15)
        at proto.<computed> [as get] (/usr/src/app/node_modules/express/lib/router/index.js:521:19)
        at OAuth.load (/usr/src/app/node_modules/nodebb-plugin-sso-oauth-faforever/library.js:91:10)

    The code in question is here:

    router.get('/api/user/oauth/:externalUserId', middleware.authenticateOrGuest, async function (req, res, next) {
    			const userId = await db.getObjectField( + 'Id:uid', req.params.externalUserId);
    			if (!userId) {
    				return next();
    			const userData = await userController.getUserDataByUID(req.uid, userId);

    I compared to other route.get and also other plugins and even our project express page, but I don't understand where the error could. I tried removing the async but no success. I also googled the error in general, but it doesn't make me much smarter.

    Any help is appreciated.

  • See this topic for breaking changes in 1.19.0 You can rename middleware.authenticateOrGuest to middleware.authenticateRequest
