> * I'm stumped because some of my local attempts are affected by the strange behavior of `org.apache.shardingsphere.mode.manager.ContextManager#alterRuleConfiguration`. The strange behavior I'm referring to ends up being something like [NPE " Cannot invoke "org.apache.shardingsphere.infra.metadata.database.schema.decorator.model.ShardingSphereSchema.getVisibleColumnNames(String)" because the return value of "java.util.Map.get(Object)" is null" #20952](https://github.com/apache/shardingsphere/issues/20952). @linghengqian This exception may be caused by wrong metadata, we will investigate it later. -- This is an automated message from the Apache Git Service.
