Error while finding module specification for 'app.main'

I’m stuck on Stage #ZV2.

it looks like the test runner cant find my code?
Running ./your_program.sh locally does work…?

Here are my logs:

Hey @Zeviraty, could you upload your code to GitHub and share the link? It will be much easier to debug if I can run it directly.

I have, the repo is linked in the main post

I have the same issue as OP has. Previous steps finish successfully, but new ZV2 fails on the early stage.

Same here

Looks like this is an issue on our end. We’re actively investigating it and will share an update as soon as a fix is available.

Hey everyone! To fix this, please update .codecrafters/run.sh to the following:

#!/bin/sh

set -e

SCRIPT_DIR="$(dirname "$0")"

PYTHONSAFEPATH=1 PYTHONPATH="$SCRIPT_DIR" exec uv run \
  --project "$SCRIPT_DIR" \
  --quiet \
  -m app.main \
  "$@"

Let me know if it still fails after the update.
