TypeError: Cannot Read Property 'handle' Of Undefined --- If (fn.handle && Fn.set) Mount_app = Fn

I would appreciate some help with this please. Not certain exactly sure what to this means as this is my first time working with node and express. I set up express to use with node

Solution 1:

The problem is that you're trying to use() a variable that isn't defined yet. If you use the function logErrors(err, req, res, next) { syntax instead of var logErrors=function (err, req, res, next) {, your TypeErrors should go away.

Solution 2:

Try to move var clientErrorHandler, errorHandler and etc before your call app.use for this.

Like:

var errorHandler = function (req, res, next) { .... }
app.use(errorHandler);

Solution 3:

Thanks i also had the same issue i was using doing this

app.use(__dirname+'path');

Instead of doing

app.use(express.static(__dirname+'/path'));

Agh ! small little typos .
