Bug description

No client is generated when prisma generate or prisma db push is run

Log

prisma db push (Cleanup was run before execution and tried to connect to db after execution)

Successfully removed all auto-generated files from C:\Users\AmaseCocoa\Desktop\Hol0\backend\.venv\Lib\site-packages\prisma\__init__.py

Datasource "db": PostgreSQL database "hol0db", schema "public" at "127.0.0.1:5432"

The database is already in sync with the Prisma schema.

prisma generate

PS C:\Users\AmaseCocoa\Desktop\Hol0\backend> pdm run prisma generate
Prisma schema loaded from prisma\schema.prisma
PS C:\Users\AmaseCocoa\Desktop\Hol0\backend>

(Logs when prisma generate is run with debugging enabled and with the latest prisma-client-py: prisma.txt)

How to reproduce

Steps to reproduce the behavior:

1. Execute python -m prisma_cleanup ?
2. Run prisma generate or prisma db push

Expected behavior

The client is successfully generated and no RuntimeError is generated.

Looks like it's failing without an error message for some reason, what happens when you run prisma generate with PRISMA_PY_DEBUG=1?

I'm out at the moment so I'll try it when I get home.

@AmaseCocoa could you try upgrading to the latest version and share the debug logs? They should now include more helpful information

I am attaching it as a txt file because it is too long and I get an error when I try to post it as a comment.

[RobertCraigie]

@AmaseCocoa I suspect this is an encoding issue somewhere, could you try generating the client using a different encoding?

e.g.

PYTHONIOENCODING=utf-8 python -m prisma generate

@AmaseCocoa I suspect this is an encoding issue somewhere, could you try generating the client using a different encoding?

e.g.

PYTHONIOENCODING=utf-8 python -m prisma generate

For some reason, I was able to get it to work by setting PYTHONENCODING to utf-8 and fixing the cp932 related error :)

I'm creating a pull request to fix the encoding error :)
