I got another error when i upgrade to latest version.

Uncaught TypeError: _interopRequireDefault is not a function

I got another bug _Reflect$construct is not defined. I tested that I found that Babel compile is correct, but there is an error after packaging webpack.

Oh thanks for investigating!
If you could share a small repository that shows it that would make it easier to fix the bug 🙏

Maybe these are the same type of errors? This can be used as a reference.

@dollysingh3192 (I'm replying here)

The PR that caused this is #12845.

Thanks btw @duan602728596 for the repo!

[nicolo-ribaudo]

This should be fixed in @babel/helper-define-polyfill-provider 0.1.1; I'll publish a @babel/transform-runtime release to make it easier to force the upgrade if someone can confirm that it works.

[nicolo-ribaudo]

I'm keeping this open until someone confirms that #12863 (comment) works and I release a transform-runtime version.

@nicolo-ribaudo ,

I checked and found that "./node_modules/@babel/runtime-corejs3/core-js-stable/reflect/construct.js" is injecting correctly 👍 with babel "7.13.0" successfully with @babel/helper-define-polyfill-provider 0.1.1 change.

But after this change jasmine test case's are failing. I raised a bug here previously where window.setTimeout and setTimeout was different. Here one is jasmine definition(which is correct) and other one is shim by babel

But now they both have same definition. Screenshot

[nicolo-ribaudo]

Thanks for confirming!

I would expect window.setTimeout and setTimeout to always be the same, since global functions (such as setTimeout) are what is defined on the window object.

However, if you want con continue the discussion about it and look for a workaround for what you need, please open an issue at https://github.com/babel/babel-polyfills 🙏 (I'm struggling to keep up with all the issue, so I'm trying to keep separate discussions in different places 😅)

[nicolo-ribaudo]

This should be fixed now
