Hey there! Since upgrading to the latest release 7.2.0, I've been seeing the following stack trace when running pytest in Azure CI:

Our Azure pipelines use the latest version of pytest and this issue was not present before this release.

• Python Versions: 3.7 - 3.9
• OS: Ubuntu 20.04

Here are some Azure logs if they'd be helpful: https://dev.azure.com/great-expectations/great_expectations/_build/results?buildId=113833&view=results

Please let me know if I can provide any additional information. Thanks for all the hard work here - pytest is invaluable to our team's efforts 🙇🏽
