Algolia + instantsearch doesn't work on IE11

[asvitlica-vega]

🐛 Bug description

We've been experiencing bugs with instantsearch and Algolia integration in IE11. We checked the docs, tried out the official polyfil.io fix, but the problem persisted.

We get the following errors: Unable to get property 'add' of undefined or null reference Unable to get property 'removeAllListeners' of undefined or null reference

FYI Our app is written in Angular 11

Hi @asvitlica-vega I believe this concerns "Angular InstantSearch", so I moved the ticket to this repository. Could you provide us with a minimal reproduction so that we can take a look at your issue? With the information given, it's hard for us to know.

@eunjae-lee it is really hard to provide you with a small snippet, but I'll try. Meanwhile, here's the exact line we're receiving an error from:

It seems like the index widget unmounts either before init was called or after it had already been removed. Are you really seeing this only on IE11? It seems unrelated to the browser

Yes, it only happens on IE11. Library versions we use (maybe they are not compatible):

• "algoliasearch": "4.9.1",
• "angular-instantsearch": "3.0.0-beta.5",
• "instantsearch.js": "4.23.0"

[Haroenv]

Yes, that's true, InstantSearch.js should be <4, so InstantSearch@3.7.0

[asvitlica-vega]

Changing the version didn't work. We're dropping the feature for IE11.

Alright, I'll close this issue then. Feel free to reopen if any change on your side.
