issue generating build for the frontend.

[Kriyanshi Shah]

while running this in the frontend directory:
npm run build
the output was.

> > frontend@2.3.7 build
> > REACT_APP_LOCAL_URL= react-scripts build
> 
> 'REACT_APP_LOCAL_URL' is not recognized as an internal or external command,
> operable program or batch file.

When I removed REACT_APP_LOCAL_URL from the build script and ran this command:
npm run build

> frontend@2.3.7 build
> react-scripts build

Creating an optimized production build...

Hi @kriyanshishah,

Please try to install packages first:

yarn install

and build with

yarn local-build

If you would like to start development server locally please try:

yarn start

[Kriyanshi Shah]

$ yarn start

yarn run v1.22.19
warning ..\..\..\..\package.json: No license field
$ REACT_APP_LOCAL_URL="" react-scripts start
'REACT_APP_LOCAL_URL' is not recognized as an internal or external command,
operable program or batch file.
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Maybe try to edit package.json to remove setting of REACT_APP_LOCAL_URL. I'm using Node 14.17.0 for development.
