The following issue arises while saving the EUM configuration, which consists of naming rules configuration:
This issue is due to the presence of some invalid rules within the configuration section for EUM app.
In this example, the include/naming rule lacks a value in the Summary Column.
Sample stack trace:
Caused by: java.lang.IllegalArgumentException: dto.type=REGEX_GROUP, but dto.regexGroupConfig.regexp=null at com.singularity.ee.controller.ui.util.URLNamingRulesMapperUtil.validateRegexConfig(URLNamingRulesMapperUtil.java:187) at com.singularity.ee.controller.ui.util.URLNamingRulesMapperUtil.mapDTOToConfigNamingRule(URLNamingRulesMapperUtil.java:32) at com.singularity.ee.controller.ui.util.URLMatchRulesMapperUtil.mapDTOToConfigRule(URLMatchRulesMapperUtil.java:51) at com.singularity.ee.controller.ui.services.eum.web.BrowserRUMConfigUiService.setPagesAndFramesConfig(BrowserRUMConfigUiService.java:177) at sun.reflect.GeneratedMethodAccessor11381.invoke(Unknown Source)
To resolve this issue, fix the invalid rules. Example solution: Ensure that there is no rule present where the Summary column is left blank.
