4.16.x cannot wrap $extend in factory function when compilerOptions.composite is true #19866
Description
Bug description
I'm trying to upgrade to 4.16.x and use the GA version of client extensions. However, now when I try to export my extended client from a file I get the following typescript error.
Return type of exported function has or is using name 'PrismaPromise_2' from external module "node_modules/.prisma/client/runtime/index" but cannot be named. (tsserver 4023)
How to reproduce
- clone https://github.com/awinograd/prisma-repro/tree/aw/extend
yarn tsc --build --force
✘ ⮀ prisma-repro ⮀ ⭠ aw/extend± ⮀ yarn tsc --build --force
yarn run v1.22.15
$ /Users/awinograd/programming/prisma-repro/node_modules/.bin/tsc --build --force
script.ts:3:17 - error TS4058: Return type of exported function has or is using name 'PrismaPromise_2' from external module "/Users/awinograd/programming/prisma-repro/node_modules/@prisma/client/runtime/index" but cannot be named.
