Hi @val722 thanks for reaching out! To help you figure this out can you answer a few questions.

1. What browser are you currently using?
2. What version of that browser are you on?
3. What version of Kibana are you running?

Thanks!

No problem @val722 - Glad it worked! For anyone else who may come across this, Firefox did not add support for `Object.hasOwn` till version 92: [Firefox 92 for developers - Mozilla | MDN](https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/92).
