Platform API 422 on nice_cxone_analytics_query filter_serialization in provider 1.21.0

The 09:00 JST sync pipeline’s doing jack all again after the dashboard migration. Terraform 1.9.9 paired with nice-cxone 1.21.0 throws a 422 Unprocessable Entity when pushing the filter_serialization block to the reporting endpoint. State drift’s cleared, tf apply retried, and the console just hangs on the metrics aggregation step.

Check your filter_serialization JSON. The NICE provider often chokes on malformed date ranges or missing type fields. Validate the payload against the /api/v2/analytics/query schema before pushing it.
