Why PlanetScale rejects it
Routing rules tell Vitess how to route queries from one table name to another table. Invalid rules can send traffic to a missing table, an ambiguous keyspace, multiple targets, or a conflicting destination rule.How to fix it
Use the routing rule location and the full error message to find the failing rule.- Qualify table names as
<keyspace>.<table>. - Verify the target keyspace exists.
- Verify the target table exists in the SQL schema.
- Use exactly one target table for each rule.
- Remove duplicate source table entries.
- Use only valid tablet-type suffixes, such as
@primary,@replica, or@rdonly. - If the error is a merge conflict, reconcile the destination branch’s routing rules first, then recreate the deploy request.
