Does not work anymore

[janterlaak]

after installation and creating a project

yarn start

/Users/j/test/myapp/node_modules/custom-react-scripts/scripts/start.js:21 throw err; ^

RangeError: Invalid string length at Object.stringify (native) at serializeMap (/Users/j/test/myapp/node_modules/inspectpack/lib/utils/cache.js:26:15) at getCacheFilePath.then.filePath (/Users/janterlaak/test/myapp/node_modules/inspectpack/lib/utils/cache.js:93:27) error Command failed with exit code 1.$

Removing the last line from the .env file does the trick

Got the same error too:

It suddenly happened while coding. It's really weird since I don't do anything to package.json or any configuration files. I commented most of my code and only left index.js, however the error still happened.

[janterlaak]

Open your .env file and remove the last line of the configutation. Save the file and run again

@janterlaak That works.

I dig out a lot bit more and find out the real problem is REACT_APP_WEBPACK_DASHBOARD in .env file. It seems the internal module inspectpack is broken somehow and effects the webpack dashboard. After remove it the dev-server would work fine.
