Make npx tsc after npm install work again

[NoopDog]

Need

A dependency or transient dependency has changed, and doing an npm install then npx tsc no longer works.
There are compile errors.

Doing an npm ci with the checked-in package-lock.json file does work. You can run npx tsc after that ok.

If you delete the package-lock and run npm install, the compile will fail.

• What is the upgrade that is breaking this?
• What fixes are required to get the compile after npm install to work again?
• What can we add to the build to test that the npm tsc runs with a new package json?
