[Bug]: CustomAnalyzerTest tests fail on macOS 13 and 14

[jrdodds]

Issue Description

Recently PR #10076 added a new CustomAnalyzerTest [Theory] with two sets of data. The PR build checks passed running on a macos-12 image.

However, when I build locally and run tests on macOS 14 on ARM and macOS 13 on Intel, the tests fail.

Steps to Reproduce

1. Run ./build.sh.
2. Run ./build.sh --test

Expected Behavior

All tests should pass.

Actual Behavior

CustomAnalyzerTest tests fail.
