Uncaught TypeError: inspectSource is not a function

[LukaszSawicki]

Hi,
after update core-js to version 3.4.5 I've got an error when using Promise.all() function.

Uncaught TypeError: inspectSource is not a function at Object../node_modules/core-js/internals/native-weak-map.js at __webpack_require__ at Object../node_modules/core-js/internals/internal-state.js at __webpack_require__ at Object../node_modules/core-js/internals/redefine.js at __webpack_require__ at Object../node_modules/core-js/internals/export.js at __webpack_require__ at Object../node_modules/core-js/modules/es.promise.js at __webpack_require__

I can see that there was an 'fix' for inspectSource in 3.4.5
Fixed inspectSource helper with multiple core-js copies and some related features like some edge cases of Promise feature detection

Before this update everything worked fine.

It was fixed in 3.4.7.

Or not? Could you check it?

Ok, I see one possible case - you use some copies of core-js, one of them - the previous version with broken inspectSource helper and your actual version inherit this helper. It's not a core-js bug, it's just a broken use case. However, I can add a workaround for that.

Okay, I found where the problem was: @babel/runtime-corejs3 was using an old copy of core-js-pure. Thanks for your answer.

@zloirock This workaround works for me, what time you will publish this unreleased version?

Soon.
