Honestly it seems just fine. Are you sure that there is a issue in the listed code? I tested it locally, and it worked just fine. Only added a PrimaryColumn and changed type of IdType.

@NKJe

PrimaryColumn

is already defined on BaseEntity, I tried everything every CrudController have same problem

[NKJe]

Well, I generated a completely clean installation using nest new ... and then added typeorm crud-typeorm and swagger stuff... and added your code, with the previously mentioned changes. And it seems fine. Made a repository: https://github.com/NKJe/prof

The use of next.handle makes me want to believe there is an issue in a middleware you are using in your stack. Can you provide a version of the library that you are using? As Nkje just said there doesn't seem to be anything in the recent releases that is causing this.

Thanks

I'm having the same "next.handle is not a function" issue. Clean app, just set up nestjsx/crud, no funky middleware or the such

@vrxj81 what's your nest version? It should be 6 at least
