I have linked Supermetrics with Google Datastudio to retrieve Facebook, LinkedIn and Twitter data. Both for organic accounts as for advertisement accounts.
When viewing the dashboard, it seems to work fine. But when I change the date range I get System errors, these system errors change from metric to metrics when I change my date range. It seems that they appear random, as for example I set the date range on last month, I get 2 system errors on my Facebook metrics, change the date and back again to last month, I get 4 system errors on my LinkedIn metrics and my Facebook metrics all of suddenly seems to work fine.
What causes these errors and how to fix this? It seems to me like an loading or data retrieving delay, because if I change the dates back and forth to the same range I eventually get all my metrics without errors.
It's possible then as you change data ranges, you exclude some "duplicate" names for some sources but then introduce some for another. I'm not sure if that is exactly what is going on, as you did mentioned that eventually you get it work with the date range you want, but this seems like a good place to start.
So I would check if you have non-unique values (Ad names, post names, campaign names, etc.) in those report elements prone to this error and see if you can add one more field that will ensure uniqueness. If you can't figure out what to do, we can help look at the file in a private email.
Thanks for the reaction. I don't think that is the case, because the error also occur for organic results, which shouldn't have the duplicate name issue. Can you check the file for me? How can I grant you access to the dashboard?
I replied with the info privately as don't want you to post links here to your file.
