ts error in turborepo + nestjs app when importing enum from outside

I have the following turborepo setup (it's the default nextjs example, with deleted docs app and added api (nestjs) app):

apps/
 api (nestjs)
 web (nextjs)
packages/
 types (ts types to share across api and web)
  src/
   index.ts
  index.ts 

Reproduction repo is here: https://github.com/jacobdo2/types-nestjs-nextjs-turbo

In packages/types, I have declared two dummy types interface Example and enum Example enum. When I import Example inside the nestjs app, it compiles fine, but when I import the enum, I get the following error:

api:dev: export * from "./src";
api:dev: ^^^^^^
api:dev: 
api:dev: SyntaxError: Unexpected token 'export'

This issue does not appear on build, but only on dev.
