GCP Deployment Manager is running yarn again (instead of using packaged file from Serverless)

[Lusitaniae]

I'm deploying two functions from my CI/CD pipeline

One in AWS, one in GCP

Both of them are pulling repos from our private Gitlab besides all the other public dependencies from npm.

It seems that after serverless packages and uploads the packge to Google Cloud, GCP Deployment Manager is running Yarn again and failing at the yarn step because it's unable to authenticate to our private repos?

Is that expected?

I'd expect a consistent behavior with AWS deployments but GCP stands out?

Including deployment tokens in package.json works around the problem, but it would be preferred not do it that way.

Hello @Lusitaniae - I'm going to move this issue to Google plugin repository as it seems more fitting there. Also, please include reproducible steps and sample serverless.yml - it will help diagnosing the problem
