I just spotted a Javascript object representation in the output of --verifytypes prefect:

   error: Type of metaclass "[object Object]" is partially unknown

This occurs 702 times in this specific project. Clearly something broke in how metaclasses are reported.

Reproduce with:

python -m venv prefect-pyright-verifytypes
./prefect-pyright-verifytypes/bin/pip install pyright prefect
./prefect-pyright-verifytypes/bin/pyright --verifytypes prefect

Context

  • pyright version: 1.1.389
  • environment: macos 14.7.1 (23H222), arm64
  • python version: 3.12.3
