Deploy to Heroku fails (closed)

[FMGordillo]

Description

Trying to deploy to Heroku an Express.js backend, from nowhere is not working anymore.
The short version:

• prisma generate fails, but I already have a generated folder, which works just fine on my local, and using PostgreSQL from Heroku.
• It gives error TS2305: Module '"../../../../node_modules/@prisma/client"' has no exported member 'Prisma'. on the build phase (with tsc)

The "long" version:

...
       > @prisma/[email protected] postinstall /tmp/build_8e0eb960_/node_modules/@prisma/client

       > node scripts/postinstall.js

       

       Prisma schema loaded from prisma/schema.prisma

       info The postinstall script automatically ran `prisma generate`, which failed.

       The postinstall script still succeeds but won't generate the Prisma Client.

       Please run `prisma generate` to see the errors.

Why do you have such weird custom output path? Could you just emit that to the folder in src but just git-ignored and see if that helps?

Sorry I didn't see your answer, I don't know either why I did that hahaha

Now I'm not using Heroku anymore, so I don't really care about this use case. It's been great on any other framework that I've used, great work Prisma team!
