Stuck on 500 Internal Server Error when querying custom attribute cust_tier via CLI. Provider genesyscloud v1.68.4, Region AU-1. The attribute exists and is populated in the UI. Query JSON validates locally.
POST /api/v2/analytics/query
{
"data": [
{
"id": "cust_tier",
"type": "attribute"
}
]
}
Response is empty. Is this a known bug or schema mismatch?
