Note that they may also be present on Hermes-debug, or Chakra-release. Our past matrix was just web debugging.

@dannyvv do you have any context on this?

[chrisglein]

@NickGerleman @JunielKatarn @mganandraj Issue has been sitting for awhile. Are these test failures still active?

[ghost]

This issue has been automatically marked as stale because it has been marked as requiring author feedback but has not had any activity for 7 days. It will be closed if no further activity occurs within 7 days of this comment.

[NickGerleman]

The test was disabled to unblock other automation. Likely still active.

[asklar]

@dannyvv is this test adding any value? If so, can you update/fix the test? If not, can you delete it?

[dannyvv]

This test is important. It tests native interop between CS modules and the JS side. It seems that there is a bug on Hermes where it is not serializing objects between a C# native model and hermes....

I'm swamped with 3 other high priority work items so I don't have time for it this week. Note if I don't respond to GH, please IM me. GH's email firehose is hard to filter properly.....
