"dmn-evaluation-result" : {
"messages" : [ {
"dmn-message-severity" : "ERROR",
"message" : "Unable to find function 'substring( lass org.kie.dmn.feel.runtime.functions.SubstringFunctio )'",
"message-type" : "FEEL_EVALUATION_ERROR",
Used below substring function in DMN DT cell:
substring (?, 3, 1) != "0"
Any insights into what I am missing here please? Thanks.
