TypeError: getBuiltIn(...) is not a constructor

--remaining || reject(new (getBuiltIn('AggregateError'))(errors, PROMISE_ANY_ERROR));

I'm using Promise.any(), and when passing my project tests with babel-jest I get the TypeError: getBuiltIn(...) is not a constructor error. Seems like it interpret getBuiltIn function as the constructor, instead of respect the parenthesis and use as constructor the result of the call to getBuiltIn('AggregateError').

.babelrc

  "presets": [
    [
      "@babel/preset-env",
      {

        },
        "useBuiltIns": "usage"
      }
    ]

The problem in built-ins definitions on the Babel side - on Promise.any should be injected also esnext.agregate-error module. So, please, open this issue in the Babel repo.

You are right, by changing useBuiltIns to entry and adding

require("core-js/modules/esnext.aggregate-error");
require("core-js/modules/esnext.promise.any");

at the top of the file (I know should not use modules directly, it was just a check) it works. Seems like getBuiltIn('AggregateError') is returning undefined, not sure if it should throw an exception with a clear message, or do a check before using the returned value...

So, please, open this issue in the Babel repo.

Done at babel/babel#10910

This got fixed in babel/babel#10930, thanks for the suggestion of writting them :-)
