Gtag.js Invalid or missing account ID

Many thanks for opening a support topic. I’ve inspected your site and your Tag Manager setup looks correct. While I can’t be sure of the Tag Assistant Chrome extension operates with new GA4 properties can you check if you’re able to view traffic on your site when accessing that property from analytics.google.com?

From previous correspondence with the team in relation to the Tag Manager Chrome extension there are changes planned, which may provide further insights for GA4 properties. I’ll check and see if I can find out more information on this and report back to you here. Note that you may wish too also pose the question on the extensions official support community. In the meantime please confirm visits are being tracked as expected.

Hi,

Thank you, @jamesosborne, for your quick reply!

I can receive traffic to the GA4 property, but the gtag.js error really concerns me. Will it affect future functionality? Is there a way to make gtag.js fire correctly or to remove it completely?

Thanks,
Berker

If you’re receiving traffic then it’s firing as expected. I’ll test the same setup from my side to confirm all is working as expected and let you know here whether I encounter the same experience.

Just a follow up on this, I’ve been able to recreate the same notice within Tag Manager using a GA4 Analytics Tag within Tag Manager, for a property that is both connected and also an individual GA4 property (not connected to a universal type property).

I can also confirm that this doesn’t impact tracking, with the Analytics property firing in both cases. You can disregard this notice within the Tag Manager Chrome extension. I’ll suspect further updates to the Chrome extension will provide further support for GA4 properties, I’ll let you know should I be able to obtain more information on this.

Just as an update to this we’re going to follow up with the Tag Manager Chrome extension team once more. I’ll keep you updated once I have any further updates on this.

@berkercimen Just to let you know that we’re spoken to the Tag Assistant team and going forward it’s recommended to use tagassistant.google.com as opposed to the Tag Assistance Chrome extension. This provides updated and improved Analytics and Tag Manager insights.
