Hey @zN3utr4l, can you specify which version of types you're using for Express and Compression?

[zN3utr4l]

{
    "name": "@types/compression",
    "version": "1.7.5"
}

{
    "name": "@types/express-serve-static-core",
    "version": "5.0.6"
}

{
    "name": "@types/express",
    "version": "5.0.1"
}

@zN3utr4l if you could provide a reproducible example, that would be great. Compression should work with both Express v5 and v4

I looked into the code and I think the problem is that the import express = require("express"); points to express 4.17.0 instead of 5.x.x

So I think the error is on the "@types/compression" package, which is here

But actually I have no clue how to fix this.

Playing around with the "@types/compression" dev dependency in my project fixes the issue somehow by itself after some attempts.

I do still not know the issue, but somehow it works again :/

i got same error since i got express 5 and "@types/compression": "1.7.5" this appear on : server.use(compression());

someone have a solution ? @snailcatcher i don't understand what u said about "playing around with the "@types/compression" ?

• I deleted the node modules folder multiple times
• I cleaned my npm Cache multiple times
• I removed and added the package multiple times

And somehow after some time ist started, not showing the error again.
