Solution to "incompatible field combination" errors.
It is possible that you have experienced an error message like this when doing your queries:
These metrics and dimensions can't be fetched together
Invalid parameters combination
Why does this error appear?
This error is external to Dataslayer** and comes directly from the data source you are using (Facebook, Bing, TikTok, Google Ads, etc).
The data that Dataslayer receives is directly calculated and sent by the official APIs of each data source. Each data source has its limitations, and there are combinations of metrics and dimensions that are not allowed, although in Dataslayer it is possible to select them.
That is why when you make your query, the servers of the data source you are using (Facebook, Bing, TikTok, Google Ads, etc) return this error, to tell you that the combination you have selected cannot be made.
Can this error be fixed?
In some cases, the error itself will tell you which metric/dimension or combination of metrics/dimensions is causing the incompatibility.
On other occasions this information is not available, so we recommend trying manually to find the field that is producing the incompatibility.
Being an external error to Dataslayer, these incompatibilities depend directly on each data source, and it is possible that they may change over time due to updates, or even disappear.
For Facebook Insights, we have developed a documentation that can help you avoid incompatible combinations.
