test case failed: could not find the expected hits in logs-okta.system-16391 data stream
```

Start by running the Okta system test named `oin` with LogsDB enabled, using the first failed Buildkite build as context. Inspect why expected hits are missing from the `logs-okta.system-16391` data stream. Done means the test reliably finds the expected hits in the system data stream.
