ear Community Members,
Need help to write defensive FEEL Expressions to filter deeply listed object structures. I’m attaching my DMN file, and exceptions while I run it in the KOGITO (Springboot) rule engine.
My target is to remove all Entry elements where entry.resource.component.extention.url ends with “SOMETHING”. Please refer to Find Observation Resources BKM in the DMN file
