TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView

Question

Our build environment currently uses node 12.19.0 and npm 6.14.8. When I saw that the new LTS version of node 14.15.1 (still npm 6.14.8) was available I downloaded it and ran our webpack build script and received this error. Is the new version of node complaining about an error that was always there, but ignored by 12.19.0?

Answer 1

Uplift jest-html-reporter version to at least 3.1.3

Answer 2

Add a second argument to writeFileSync

Instead of:

fs.writeFileSync(`${folderName}/styles.css`);

Do this:-

fs.writeFileSync(`${folderName}/styles.css`, '');

It tells wfs what to write to the file. It can be left empty
