Related Issues

After the update to @babel/preset-env ^7.8.6" I faced the exception during the build on a plain machine using NodeJS 13.13+:

ERROR in ./core/service-worker/index.js Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Cannot find module '@babel/compat-data/corejs3-shipped-proposals'

I've found this issue mentioned in the latest commits of the babel plugin and upgraded to 7.9.0 as recommended: babel/babel#11283 and nodejs/node#32852

Short Description and Why It's Useful

Support the latest NodeJS version.
