我正在使用WSO2 API Analytic 3.1.0。我总是在日志文件中看到以下异常：
TID: [-1234] [] [2018-08-20 15:20:45,020] ERROR {org.wso2.carbon.analytics.spark.core.AnalyticsTask} - Error while executing the scheduled task for the script: APIM_USER_AGENT_STATS {org.wso2.carbon.analytics.spark.core.AnalyticsTask}org.wso2.carbon.analytics.spark.core.exception.AnalyticsExecutionException: Exception in executing query INSERT INTO TABLE APIUserBrowserData SELECT api,version,apiPublisher,tenantDomain,total_request_count,year,month,day,requestTime,os,browser FROM API_REQUEST_USER_BROWSER_SUMMARY_FINAL

哪个列是clob？我不了解什么是column key_os_browser_facet，以及查询中如何填充它。
INSERT INTO TABLE APIUserBrowserData SELECT api,version,apiPublisher,tenantDomain,total_request_count,year,month,day,requestTime,os,browser FROM API_REQUEST_USER_BROWSER_SUMMARY_FINAL;
问题与本专栏有关吗？ 如何在WSO2分析中调试脚本？
编辑： 我发现问题与os和浏览器参数的空值有关。我在选择查询中使用了if（os为null，“ UNKNOWN”，os），if（browser为null，“ UNKNOWN”，浏览器），并且在选择查询中也没有抛出异常。我的问题是，当我重新启动Analytic Server时，脚本已被重写，并且原始脚本，浏览器和os都没有if-null条件，而是替换为我的脚本。如何在启动分析时避免此问题？
