React Js : Module parse failed: Unexpected token

I keep getting below error in my react app. Not sure what is the issue.

/Users/823222/miniapp/node_modules/headers-polyfill/lib/Headers.js 9:25 Module parse failed: Unexpected token (9:25) File was processed with these loaders:

[NORMALIZED_HEADERS] = {};

| // Keeps the mapping between the raw header name | // and the normalized header name to ease the lookup.

Looks like this is due to a recent change in this package, that changed how the symbols were declared:

https://github.com/mswjs/headers-polyfill/pull/33/files

I've started a GitHub issue here, feel free to add details about your environment: https://github.com/mswjs/headers-polyfill/issues/36

TL;DR: There was a significant change to how the module is prepared in a recent release, I reverted to 3.0.4 and things are working again for me.

Edit: 3.0.10 released that reverts the build target and fixes this issue: https://github.com/mswjs/headers-polyfill/releases/tag/v3.0.10
