Unable to deploy Vapor Project using GitLabs CI

Hi,

I was able to get this working on a previous project but with this one, I am having a weird issue.

Using GitLab's CI, I am unable to deploy the project using vapor deploy: production, however staging works without any issues.

When deploying, Vapor times out at "updating function code" with no errors showing up in the usual places.

The same codebase can be deployed locally to production, and the CI can deploy to staging but not production.

Any advice on where to start debugging this one?

Vapor.yml:

            - 'php artisan event:cache'
            - 'npm install && npm run production && rm -rf node_modules'
        deploy:
            - 'php artisan migrate --force'
    staging:
