Hi Alberto,
We observe the same error querying user_interest, so it's likely that the problem is not in your request, but in unexpected API behaviour.
Additionally I get the same
{ "message": "Internal error encountered.", "code": 13, "status": "INTERNAL", "details": [ { "@type": "google.ads.googleads.v15.errors.googleadsfailure-bin", "data": "" }, { "@type": "grpc-status-details-bin", "data": "" }, { "@type": "request-id", "data": "l_kDV3MB5aLDGBd_xbPIzQ" } ] }
querying detailed_demographic:
Google Ads API team - please let us know what's going on with user_interest data view.
Thanks,
Oksana
