sharing artifacts across stages in codebuild breaks npm commands

[s1mrankaur]

npm scripts like

`test: 'react-scripts test'

`works just fine if the build stage of the code pipeline.

If I use artifact from build stage as an input for deploy stage and run

npm run test It fails in the deploy stage with the following error:
`

CI=true react-scripts test --env=jsdom --no-cache internal/modules/cjs/loader.js:818 throw err; ^ Error: Cannot find module '../scripts/test' Require stack: - /codebuild/output/src177948730/src/node_modules/.bin/react-scripts at Function.Module._resolveFilename (internal/modules/cjs/loader.js:815:15) at Function.resolve (internal/modules/cjs/helpers.js:80:19) at Object.

`
If I change the script to

"test": " ./node_modules/react-scripts/bin/react-scripts.js test ", This works okay in the deploy stage but not in the build stage. What is happening? How can I fix it?
