Failed to parse source map from .../signing-key/lib.esm/browser-elliptic.js.map

I have a project that uses yarn and webpack, and includes ethers as a dependency. When I start the project via yarn, I see this warning:

WARNING in ./node_modules/@ethersproject/signing-key/lib.esm/elliptic.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/Users/jimmie/Projects/Lazy3d/frontend/node_modules/@ethersproject/signing-key/lib.esm/browser-elliptic.js.map' file: Error: ENOENT: no such file or directory, open '/Users/jimmie/Projects/Lazy3d/frontend/node_modules/@ethersproject/signing-key/lib.esm/browser-elliptic.js.map'

I've determined that if I change this line:

ethers.js/packages/signing-key/lib.esm/elliptic.js

Line 2478 in ce8f1e4

//# sourceMappingURL=browser-elliptic.js.map

to simply:

//# sourceMappingURL=elliptic.js.map

the warning disappears.

I don't really know enough about this project to know if the line is incorrect as is, or if I've configured something on my end that is misinterpreting it. Also not really sure how this lib.esm folder is getting generated. Any thoughts would be appreciated, happy to submit a fix if I can get some guidance. I suspect change that line is not the appropriate way to fix it.

Thanks!

Fixed in 5.5.0.

It was a missing /m in the regex of the aliasing script. :s

Thanks! :)
