I’m having trouble finding a GTM error. The error states that Google Tag Manager isn’t receiving the URL/page-name in Google’s Behavior->Landing Pages report before it receives an event.
I’m not sure how to find the offending page and of course, Google can’t tell me the offending page, so trying to use Google’s Tag Assistant would mean testing every single page on the website.
The error appears to be happening on all of the major browsers, so it doesn’t seem to be browser specific.
I tried to lookup one session by matching the session duration with user sessions. The session begins at 11:58 pm and ends at 12:04 am. However, when I use Google’s Tag Assistant, it doesn’t show any errors.
If this were the problem page, it would appear that GTM looses the page name when the session wraps over the midnight hour, but this seems improbable.
How can I properly identify the offending page without using Google Tag Assistant on every single page?
