I follow documentation about adding Google Tag Manager into project https://developers.google.com/tag-manager/ios/v5/. I added container folder to my project's target but I am still getting some warnings from GTM to log and it is not possible to track events to Firebase.

GoogleTagManager warning: Can not retrieve container from network. Response: 404 GoogleTagManager warning: Event emitted before runtime was initialized.

What is the proper way to initialize Tag Manager? I use my "containerName" + .json as name of the container file and add them to folder "container".

GTM iOS SDK 7.1.1

Thanks.

Hi, did you manage to solve it? – DaNLtR
Hello. Yes, When you download container, his name looks like "GTM-id_v1.json". I just deleted "_v1" and its solve my problem – Dima Paliychuk

Referring to this link, the name of the file should be GTM-XXXXX.json. When its downloaded, it could be something like GTM-KZ4ZT31_xxxxxx.json so you just need to get rid of everything after the id, for example this GTM-KZ4ZT31_xxxxxx will become GTM-KZ4ZT31.json.

Also, double check to use the latest container file generated from the TagManager
