Description

We started getting the error in production like 3 weeks ago, and it is constantly failing, mostly for Apple devices using Safari/Safari Mobile.
The sentry logs show the error comes from customer IO integration.

What should we do to fix it? Is there any workaround?

We are using Analyticsjs 2.0.

Thanks!
