[Paul-AUB]

Same error here with same version.

[abi-jey]

Same issue here after the update.

[EtcetFelix]

likewise, same issue. Had to downgrade to the Python extension 2024.8.1 release to get my test configuration to work.

[eleanorjboyd]

dup of #23707, look there for solutions. You likely need to upgrade your pluggy version for the best results.

[Paul-AUB]

Well, already have pluggy==1.5.0 (which is the latest version), and it's not working. I'm not sure it is the same issue as #23707 (not the same traceback, not the same versions).

In the current issue, it seems that the extension is trying to use code deprecated by pytest in the latest versions, cf https://stackoverflow.com/questions/62762845/attributeerror-module-pytest-has-no-attribute-config.
It seems that the extension bumped the upper bound of pytest but the code is not compliant with it.

Missing references are :

• pytest.Config
• pytest.PytestPluginManager
