Bug: Error loading source maps for devtools extension

[Friss]

React version: 16.x.x

Steps To Reproduce

1. Have latest React devtools installed in Chrome
2. Open console and see warning about failure to load source maps.

Looks to be related to #19773

Link to code example:

The current behavior

I have the same warning, and my componet is always loading.

but it works on 4.8.2

I have the same warning in React^17.0.0 too

[bvaughn]

Sorry about the hassle here. I'm not sure why Chrome is showing this warning, as the source map URLs are correct. If anyone would like to dig into this, I'd welcome the help.

@hqwuzhaoyi Your comment does not seem related to this thread. If you're seeing a problem with a component's props loading, please file a separate issue with repro instructions.

Looks like a potentially related CR bug from back in February: https://bugs.chromium.org/p/chromium/issues/detail?id=1052872

[bvaughn]

A simple fix for this might be to revert the changes from #19773 to files within packages/react-devtools-extensions (but leave the other packages with source maps enabled).

@bvaughn I tried reverting the changes in packages/react-devtools-extensions and it fixed. Please help to review the PR #20079. Thanks.

Thanks for the quick work @bvaughn @sytranvn

We've run into similar issues with our own chrome extension so no big deal :D
