Express 5: Optional Parameters (TypeError: Unexpected ?)

[SupertigerDev]

I have a route like this /users/:userId? which worked fine in express 4

but i get this error in express 5. It is understandable that I need to use the new format, however, the error does not provide a line number, making it difficult to find in my existing codebase.

Also, what even is the new solution to this?

use /users{/:userId} instead

If I have 1000 routes, how do I easily replace it everywhere?

[wenerme]

maybe editor replace :(\w+)[?] -> {:\1} ?

This also works and IMO clearer/cleaner ["/users", "/users/:userId"]
