Hey 👋 Thanks for creating your first issue - Someone will get back to you on this shortly.

Hi @silencej ,

Are you using typescript in your project ?

You would need to set the target to es6 in tsconfig.json

{
    "target": "ES6",
    // ...
}

Hi @silencej - Can you try 3.0.0-beta.3 as well to see if you still see the issue ?

Thanks - V

@vip-git I confirm that the issue is gone in beta.3. Thanks for fixing this!

[vip-git]

Thanks for raising this as well @silencej .

It looks like this is a problem in 3.0.0-rc.5

Also, not using typescript, this is from a clean CRA
