@khareyash05 for me it seems correct, I do not understand what @Creatoon said respect to the error messages. Can you update the conflicts to make it work again with the latest changes?

Once you do that I will merge your PR.

Resolved the conflicts. Maybe we are unable to comprehend what @Creatoon wants to say. If there is something I might be missing. Let me know. Thanks @viferga

I passed the CI and after my change of considering all warnings as errors (of the linter), your CI execution failed: https://github.com/metacall/faas/actions/runs/8294111642/job/22775896259?pr=38

Correct this linter issue and I will merge it.
