serverless: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

Hello,

We’re trying to migrate to Serverless. Unfortunately, it looks like sls package -s dev just dies. We have a large project consisting of over 50 microservices. It seems that webpack is the issue when Googling, but no one really knows, nor does anyone have any good documentation on how to resolve this issue. If this has already been solved, please add a comment in the readme, so others can use this exciting tool.
