I keep getting this error on "npm run build" from this particular file
node_modules/@types/serve-static/index.d.ts:98:67 - error TS2709: Cannot use namespace 'HttpError' as a type.

Node version : 18

The two libraries dependent on serve-static in my dependencies are firebase-functions and express

This is my package.json

@benasher44 Appreciate if you could take a look!

[benasher44]

@PuneetKohli why me? I'm not a maintainer of these types, and this doesn't look connected to types I've updated recently (e.g. validator). Could you clarify why me? Maybe I'm misunderstanding though

[PuneetKohli]

Saw you recently helped resolve a somewhat similar-looking issue (#68152) in [@types]/validator. If you are able to help that'd be great! Otherwise, please let me know the right maintainers to tag :)

[PuneetKohli]

(Been grappling with this issue a few days now, as we don't use these libraries directly, it's a dependency from express and firebase-functions, and it's completely blocked from moving forward w/ other packages we are trying to use. The issue comes up when we upgrade typescript.)

[benasher44]

Ah i see. While both issues deal with namespaces, this one is different. If you file this via discussions, the bot will automatically tag the right maintainers.

Appreciate the help: @urossmolnik, @LinusU, @devanshj.
