Failed to parse source maps

[jelhouss]

Hi @willryan, thank you for your awesome work.

I have been using factory.ts since last year to generate fake data with Faker, with no issues.
However, as I am now using create-react-app v5, I came across warnings related to source maps not being available for factory.ts every time I compile my app.
Currently, they are shown as warnings in development mode obviously, but not sure if they could occur in production as well. I don't know.

The warnings follow this pattern: Failed to parse source map from (files under /src)

For CRA, I found this discussion. Apparently, a lot of folks are using libs that don't expose source maps, and CRA is complaining about that.

Using an env var for CRA like GENERATE_SOURCEMAP=false would eliminate those warnings (for all third parties actually, not just a specific target) however, I don't find it practical to use that. I'd like to enable source maps for factory.ts.

I can see in tsconfig.json that "sourceMap": true is commented under compilerOptions, is there any reason for that? Is that by choice?

My factory.ts version is 1.3.0, and I am using Node.js 18

Hi @jelhouss,

I switched from sourceMap to inlineSourceMap 4 years ago, but to be honest I don't remember the context. I have never really used create-react-app, but I'm open to changing the style of source maps if it makes spurious warnings go away. I would just want to make sure debugging still works in VSCode etc. If you can verify that, feel free to make a PR and I'll approve it.
