Deploying to production breaks at 'building the application' step all of a sudden

Deployed over 100 versions without problems, last one about 12h ago and now it breaks. See details below:

Anyone else having this problem? It only happens are my deployment for my server (backend) only. The deployment for my frontend (I have two separate apps for each) runs perfectly fine.

Thanks in advance,

Andreas

Solved it. Whilst upgrading bcrypt it somehow deleting some other dependency. All working now
