Current Behavior

When upgrading LocalStack to v0.12.17, Node.js tests in GitHub Actions cannot connect anymore

Expected Behavior

Upgrading to v0.12.17 doesn't break the tests

How are you starting LocalStack?

With a docker-compose file

Steps To Reproduce

Go to this page https://github.com/micheleangioni/sls-node-ts/commits/testBranch

Tests running at commit 79dc94d23d3cf2c94ea5d2aa4254168fe75946b6 with LocalStack v0.12.16 run without problems https://github.com/micheleangioni/sls-node-ts/runs/3863736562

Just updating LocalStack to v0.12.17 is enough to break everything, see micheleangioni/sls-node-ts@fb7c863
tests failing here https://github.com/micheleangioni/sls-node-ts/runs/3863773280

Environment

GitLab CI conf: https://github.com/micheleangioni/sls-node-ts/blob/testBranch/.github/workflows/ci.yml

docker-compose: https://github.com/micheleangioni/sls-node-ts/blob/testBranch/dev/docker-compose.yaml

Anything else?

There are no breaking changes in the release notes. v0.12.18 is broken as well.

Please, let me know if I can support with the investigation.

Thanks
