A month ago or more, as I was developing my site I noticed this error referencing react. I don’t use react code. The error appears to be related to a webhook but it is not in my site or code and appears to be Webflow.

I’m not able to see that error in the console when going to your site:
Shared with CloudApp

Can you confirm if this is still happening on an incognito mode window with all browser extensions turned off?

I think David might be referring to designer mode?
