Current behavior

I can't detect within the middleware if the route exists, my auth module based on path, so naturally all requests become 401 thought it's 404, it's very confusing for users.

Expected behavior

404 happens before middleware or there is a way to detect it during middleware and throw a 404 error manually.

Minimal reproduction of the problem with instructions

in the middleware I'm doing that:

const permissions: IPermissionsResult = await perms.isAllowed(key, replaceDelimiter(req.baseUrl), mapActions(req.method));

if (!permissions.granted)
next( new UnauthorizedException('error message goes here'))

changing it to throw also didn't help, so the only solution I have is to put error flag to request as a parameter and then throw it there, which is ugly.
I did implement the BaseExceptionFilter, but it also caught only the error I throw, not the 404 error.

What is the motivation / use case for changing the behavior?

I'd suggest tracking this issue #1030 which should enable generation of all routes defined in your app (then you could simply iterate through an array and in case of a missing endpoint, throw 404 error)
