Errors in the start script

Error 1

(cd $APP_FOLDER/rule-manager/rule-manager-client && npm i && npm run build)
"Must move up a directory to execute npm" should be:
(cd ../$APP_FOLDER/rule-manager/rule-manager-client && npm i && npm run build)

Error 2

Line 39 sbt "checker / run" causes this error

After changing sbt "checker / run"
To
sbt "run"
I'm getting this error

Also the project assumes webpack and sbt are installed on the host machine, the start script should check if those packages have been installed, if not then install or document to install the packages.
