Are you using any aggregation rules?? Also have you already set up Rapid setup configurations??
Sometimes I used to get the same error, a simple fix for me was to remove the rapid setup configurations, and then set it up once the aggregation was done…
@pbobadil do you have Service principle and Serviec plan in schema ? Also, check if in schema if you have riskLevel, riskState, riskDetail, riskLastUpdatedDateTime. Sometime create this attributes so try to remove then try. Also creationType - remove this also.
