Description

We updated one of our projects from @zeit/ncc to @vercel/ncc and get a runtime error "TypeError: Cannot read property 'split' of undefined" since then. I could nail it down to a function import from @azure/ms-rest-nodeauth.

The attached file contains a minimal project demonstrating the error. To reproduce it, please execute these commands:

tar xvzf ncc-test.tar.gz
cd ncc-test
npm i
npm run build
node dist/index.js
--> the error message is displayed

When going back to @zeit/ncc, the error doesn't occur anymore:

npm uninstall @vercel/ncc
npm i @zeit/ncc
npm run build
node dist/index.js
--> the expected output "function" is displayed

ncc-test.tar.gz

Research direction

Extract ncc-test.tar.gz and run npm i, npm run build, and node dist/index.js to reproduce the error. Compare the @vercel/ncc build with the @zeit/ncc build in the minimal project, then confirm that the @vercel/ncc output runs and prints "function" without the split error.
