Update to 12+ works with an exception

[Mo Moadeli]

I cloned this repo, updated to ng 12+, and ran npm run start (kicks off shell, mfe1, mfe2) When I click on any of the side panel items to load an MFE I get an excepetion. I have attached the error as a screenshot. Below is the exception text pasted too:
