Parameter count mismatch - due to babel polyfill

To support IE11, I had to add <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.4.4/polyfill.min.js"></script> to my .aspx file.

But this throws this error in console.

Uncaught Sys.ParameterCountException: Sys.ParameterCountException: Parameter count mismatch.

How can I solve this error without removing Babel-polyfill script?

If I don't add that script for babel-polyfill, the error is not thrown.

You can also try to not use babel-polyfill and use core-js with regenerator-runtime instead.

According to official docs, babel-polyfill has been deprecated

As of Babel 7.4.0, this package has been deprecated in favor of directly including core-js/stable (to polyfill ECMAScript features) and regenerator-runtime/runtime (needed to use transpiled generator functions):

And a preferred way to polyfill browser functions is to include packages regenenerator-runtime and core-js which you can find on https://www.npmjs.com/ and then include them at the entrypoint of your react/angular/etc. project

import "core-js/stable";
import "regenerator-runtime/runtime";

https://www.npmjs.com/package/regenerator-runtime

https://www.npmjs.com/package/core-js

Try to add ScriptMode="Release" to the ScriptManager. Look at ZariffS reply for similiar problem https://github.com/handsontable/handsontable/issues/4599#issuecomment-343506686
