During the occurrence of some ecommerce events, an error appears in the console for google services (this is about Google Tag Manager). This error causes the remarketing tags in google tag manager to stop working in the 'still running' state and cannot complete the task. This causes us to not collect remarketing lists. The error generally, from what we've read, can indicate an incorrectly configured query sent to Google services (e.g. an error in the GTM container id or conversion id) while this is already verified and for sure the conversion id is given correctly.
Suspicions fall on cache plugins or a problem with cookies on the site. On the other hand, we are not able to verify this.
