Yandex.metrics groupings?

Question

API

Today after lunch, the script that accesses Yandex.metric and receives an array stopped working, the request uses groupings

"ym:s:lastSearchPhrase", "ym:s:lastSearchEngineRoot", "ym:s:startURLPathFull", "ym:s:regionCountry", "ym:s:regionCity", "ym:s:deviceCategory", "ym :s:operatingSystemRoot", "ym:s:browser", "ym:s:hourMinute"

if I remove 4 groups, these are the ones that work

"ym:s:startURLPathFull", "ym:s:regionCity", "ym:s:operatingSystemRoot", "ym:s:hourMinute"

otherwise
"data" : [ ],
, until today, there were no problems, approximately 2-4 months of use, the token is correct, I looked at the Yandex.metrics blog - there have been no updates since July...
