npm build fails

[layik]

This is becoming an annoying issue.

Error:

./src/App.css
Module build failed: BrowserslistError: Unknown browser query `dead`

Cause: Removing the mentioned css file from the project DOES build.

Diagnosis: Not happening during npm start Happening across platforms

Also happening if CRA is upgraded to 2.0

This should not be relevant to us, we are not using "bootstrap" npm package only the cdn package.

Strange, with "clean" run of the front end direct from inst files builds. Almost there.

1 full day later: npx create-react-app (CRA) creates a package.json with following without which CRA is not happy and gets created with our "semi automated" gp_build function.

  "browserslist": [
    ">0.2%",
    "not dead", <============ culprit
    "not ie <= 11",
    "not op_mini all"
  ]

we copy our package.json over it and when we run npm run build it does not like that not dead.

Is this nightmware over? :) next commit will tell.
