NOTE: Parcel bundler Invalid Version

[brianAxonify]

There is an issue on "parcel-bundler": "1.12.4" that causes this issue. If you are having this issue a quick fix is to use
"parcel-bundler": "1.12.3", in the package.json and then run npm install

This issue is being worked on in parcel
parcel-bundler/parcel#5943

Thanks - I got a semver (invalid undefined) error and it was due to this. Your solution didn't work for me, but found something similar on stackover flow that worked:
