Using Amplify to deploy my React app (created with create-react-app) and I get the following error.

I checked the solution provided here AWS Amplify: DevTools failed to load SourceMap: Unexpected token < in JSON at position 0 but that is already configured as such.
Thanks to a colleague's assistance, this resolved this issue.
Add "GENERATE_SOURCEMAP=false to the "build" line:
Before
"build": "react-scripts build",
After
"build": "GENERATE_SOURCEMAP=false react-scripts build",
