Integration testing failed

[boldpulse]

For the issue, #764, I resolved by reducing the error level to warning from errors. The code change is just modifying error to warning with one line.

Here is my code change.

But, it is failed in the integration testing while CI/CD.

Here is my PR for showing the error. https://github.com/TraceMachina/nativelink/actions/runs/8895639436/job/24426412845?pr=894
