Problem with storyline quiz and lms problema

I created a storyline quiz and imported it to the lms platform with the scorm 1.2 format. I manage to launch the module, but at the end, the page of the result does not appear. I tried on cloudscorm and it's works. I tried to request a debug log and the message that : 
{"message":"Request processing failed; nested exception is org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'timestamp' cannot be found on object of type 'java.util.HashMap' - maybe not public?","error_id":"de05e9a6-1ce4-4977-ae54-f8eae2f5736c"}

Someaone can help me?
