Error including local npm module

[janoist1]

I'm getting errors when using local npm package:

...
"common": "file:../common",
...

Serverless: Packing external modules: aws-sdk@^2.270.1, uuid@^8.3.2, ramda@^0.27.1, common@file:../common, atob@^2.1.2, es6-promisify@^6.1.1, btoa@^1.2.1, node-forge@^0.10.0, slugify@^1.4.6, node-ses@^3.0.3, request-promise-native@^1.0.7, request

  Error --------------------------------------------------

  Error: ENOENT: no such file or directory, stat '/Users/i/Dev/name-of-project/api/.webpack/dependencies/node_modules/common'

I'm pulling my hair as Serverless ecosystem keeps throwing 'random' errors at me. This is the most recent one blocking me.
