I think this is an issue of source-map-loader rather than time-ago, you could just try to ignore this warning referring to this doc.

See: facebook/create-react-app#11924 (comment)

The problem is that the library's source files are being referenced but not being published, just the compiled code in the dist directory. I'm also having this issue with zod, there's an open issue about it and a PR to publish the source files which would fix the problem.

@hustcc I would re-open this. I think you need to publish the source, otherwise it's impossible for the source maps to be applied, and any debugging that hits source in this module will be very difficult to follow.

[garfieldnate]

Also, note that this fix needs to be applied in the timeago package, as well.

any solutions?

Solution add .env GENERATE_SOURCEMAP=false

Solution add .env GENERATE_SOURCEMAP=false

Not worked for me. And i don't think this is an elegant solution
