I’m using nestJS. When I start the project, I have the following error. Is it a problem from the @types/express package ? Or is it something I did wrong ? Thanks.

I had the same problem with compilation, though just deleting package-lock.json didn't work for me. However, this did: npm update @types/express-serve-static-core --depth 1... It's suggested in the linked issue

as mentioned here, just remove the package-lock.json, and reinstall packages.
