Hi @jacobhaile!
Thanks for taking the time to open this.
Since we're targeting Node 14 as the minimal engine and optional chaining is available from Node 14, I believe this change is not needed.
Thanks again!

Thanks for the time @MatanBobi!

Does this account for esm files? I upgraded react-testing-library to v14 and I'm seeing my cypress runs impacted because of that optional chaining syntax. I'm on node v16.

That's a good question @jacobhaile, I must admit I'm not entirely on the ESM train. I'll have to look into it a bit more. Not sure I'll have the time for it soon so I'm opening this PR and if someone has an opinion, they're more than free to post it :)

@MatanBobi I believe this is correct.

@jacobhaile I can't reproduce this issue with Cypress. Can you please share a reproduction?

[jacobhaile]

I can close out -- I no longer get the error after updating to Cypress v13

[MatanBobi]

Thanks for the update @jacobhaile :)
