[CI] SearchableSnapshotsIntegTests.testCreateAndRestoreSearchableSnapshot failing

[mark-vieira]

This looks to be a newly added test suite which has been regularly failing. There are actually two different failure messages for this test, but they're likely related so I'll put them both here.

The first did not reproduce for me:

This one did in fact reproduce locally:
