Trying to update participant attributes mid-call via PATCH /api/v2/conversations/conversations/{conversationId}/participants returns a 400 Bad Request. The JSON payload looks correct:
{
"participants": [
{
"id": "abc-123",
"attributes": {
"custom_priority": "high"
}
}
]
}
The error message just says “Invalid request body” with no details on which field failed. Anyone see this?
