Started getting TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined in multiple CRA projects after dependency updates today.

Updating react-scripts solved the issue in my unejected apps, but I still have no solution for ejected ones. I've tried updating react-dev-utils manually but am still seeing it on yarn start - anyone with ejected CRAs have this issue?

Edit: Downgrading react-dev-utils to 10.0.0 resolves the error for ejected apps in development mode only, but will not work in production or served over HTTPS due to #8075 which was not fixed until after 10.0.0.

Edit 2: @syberen said:

I solved it the hard way, by creating a new react app, ejecting, and copy-pasting the relevant changes in the config and scripts into my ejected project.

^^ works fine for ejected apps
