WSo2 APIM 1.10.0和DAS 3.0.1

Question

我试图整合APIM 1.10.0和DAS 3.0.1。我正在运行一个docker-compose，每个APIM产品配置文件都有一个docker容器。我按照步骤配置文档中概述的APIM和DAS。我确保在APIM和DAS中都配置了stat_db连接。我在DAS日志中看到以下异常。有人能让我知道可能是什么问题吗？

ERROR {org.wso2.carbon.ntask.core.impl.TaskQuartzJobAdapter} -  Error in executing task: Analytics Relation created with an empty schema for tableORG_WSO2_APIMGT_STATISTICS_THROTTLE   

ERROR {org.wso2.carbon.ntask.core.impl.TaskQuartzJobAdapter} -  Error in executing task: Analytics Relation created with an empty schema for tableORG_WSO2_APIMGT_STATISTICS_REQUEST

此外，看起来APIM首先在发布活动时遇到了麻烦。以下是APIM日志中的例外情况，这里是完整的堆栈跟踪
