Hi all, I'm getting a

TypeError: 'list' object is not callable

on unit tests running during a ci pipeline. I didn't make any changes to the tests or resources being tested, but I am working through a pulumi-azure-native migration from v1 to v2. I was seeing this unit test error pre migration as well though so I'm not completely sure what's causing the failure. The line it's failing on was added somewhat recently so I figured I'd call it out here: https://github.com/pulumi/pulumi/commit/5685291373b906c6a91b0986310eaefcab9264ff Failure:
