DevTools failed to load SourceMap from @apollo/client

DevTools failed to load SourceMap: Could not load content for 
webpack:///node_modules/@apollo/client/utilities/observables/Observable.js.map: HTTP error: status code 404, 
net::ERR_UNKNOWN_URL_SCHEME

Intended outcome: I just added the apollo/client to my Webpack/TS/React project and now I have a tons of warnings in my devtools. I can use some hack to ignore them, but you might wants to know about this inconvenience.

I also added ‘source-map-loader’, and now warnings had change:

./node_modules/@apollo/client/version.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/Users/ruafjxn/rayf/custody-rbo-widget/node_modules/@apollo/src/version.ts' file: Error: ENOENT: no such file or directory, open '/Users/ruafjxn/rayf/custody-rbo-widget/node_modules/@apollo/src/version.ts'

Actual outcome: There is not any warnings.

How to reproduce the issue: Just import apollo/client and run a project with webpack. I use webpack@4

Versions npx envinfo@latest --preset apollo --clipboard

Any solutions to this yet? Its very spammy as it has a lot of files, so its a bit frustrating
