在PGSQL（9.5）数据库（具有共同的WSO2AM_STATS_DB数据库）上连接wso2am-2.0.0和wso2am-analytics-2.0.0，我们收到以下异常：
TID: [-1] [] ERROR {org.wso2.carbon.ntask.core.impl.TaskQuartzJobAdapter} - Error in executing task: Error while saving dat

PDATE SET total_request_count=EXCLUDED.total_request_count, time=EXCLUDED.time was aborted: ERROR: null value in column "apipublisher" violates not-nu
ll constraint
完整例外是here。
根据日志，直接原因是 apipublisher 字段 null 不应发生的事情。
所以现在我有几个问题：
我该如何预防？如何配置apipublisher值？我如何摆脱无效数据
感谢您提供任何提示
