I get a message where it says the tag needs data.gtmOnSuccess() or data.gtmOnFailure()
How to fix this?
Going to use it for our blog: https://asento.dk/google-tag-manager-guide/ But won’t write something that’s not correct…
I’ve instead tried to use GA4 as the Data tag and used the GA4 Client for this configuration. In here, I could type exactly which event parameters I wanted and name them as I wanted. I think this alternative to the Data Tag and Data Client templates would work fine for all that need to send custom data to Server GTM!
Hi Benjamin,
Could you elaborate a little bit please? Where exactly are you getting that message?
Ideally a screenshot of the inside of tag and/or full view of fired tag in debug mode would be best to figure it out.
Data Tag is used by literally hundreds of people here and it does work, I assure you

Thats also why it seemed to be in that specific tag Manager account.
The error messages appeared in the Console, but now everything looks fine, so maybe it was a temporary bug. 
Hi @Dan , I am having same problem not sure how to fix this.
Data Client is not a tag, but a Client. It seems you’re trying to import it as a tag template instead of the Client one
