Hello,
I'm monitoring a site's issues using Sentry and there's a persistent issue that is coming up in the reports: 'ReferenceError - Can't find variable: zE.
This is implemented with GTM with only 2 tags, the Zendesk widget and another cHTML tag using the zE variable. I've already tried firing the Zendesk Widget before the cHTML tag with tag sequencing to make sure that the zE variable is defined and also changing the tag firing priority, but the issue persists.
What's tricky about this issue is that it doesn't happen all the time, for all devices. I could only replicate it for an iPhone X where I saw the error in the console, otherwise, I am only aware of these errors through our website monitoring tool.
Any ideas?
Thank you.
