Hi @jrock2004!

I was facing the same issue, and a comment from #1030 solved my problem: #1030 (comment)

[kettanaito]

Hey, @jrock2004. This looks like a duplicate of #1030. There's a suggestion on how to circumvent these warnings from @washingtonsoares above.

We have the issue to publish the source code of @mswjs/interceptors to NPM so webpack can build its source maps (see mswjs/interceptors#196). You are welcome to help us with that, if it sounds interesting to you.
