It is very hard to understand what is happening, in what context did this happen? What versions of node etc were you running?

[sewolf]

i hava a typescript project created with create-react-app and installed diff2html v. 3.4.17 (node v18.3.0). When i start the development server with "npm run start" the i see this warnings.

👋 Version 3.4.17 does not exist, can you double check that? Also, can you provide maybe a snippet or a script to replicate the error?

here is also the 3.4.17 version https://www.npmjs.com/package/diff2html/v/3.4.17

So seems like it does not fail. It just throws warnings. I have no idea why it is looking for source maps or even how to generate them.

I am just using regular webpack to build the project. If you know how to fix this let me know. But honestly not sure why it would show warnings if they do not exist.

here is the same problem described: https://stackoverflow.com/questions/70599784/failed-to-parse-source-map i have also added GENERATE_SOURCEMAP=false in .env file to remove this warnings
