When I execute this, I have an excepiton saying : org.flowable.common.engine.api.FlowableException: DMN decision with key helloworld execution failed. Cause: condition expression returns non-Boolean: 10 (java.math.BigInteger) in Execution[ id ‘PRC-c2d2ce2d-ec2e-11ee-9143-02420a82c03b’ ] - definition ‘PRC-dmnHelloWorld:17:be54c070-ec2e-11ee-b62d-02420a82c010’

could you please help me fix this?
