Integration tests fail but build pipelines still pass

[dtcaciuc-ggs]

I noticed this because I was going to make a PR and was trying to run integration tests, which were failing. I then checked a successful pipeline and noticed they're failing there as well in the same way

For example in https://github.com/DataDog/datadog-serverless-functions/actions/runs/10471442547/job/28998735949
