The page 'Experience Journey Map' in EUM component shows an error message

[hamed.khosrawi]

Hello Sir/Madam,

I am using the on-permise version of the Appdynamics platform. I'm going to check the last features of the EUM component for a web application.
While checking the EUM data, everything is OK but the page 'Experience Journey Map' shows the following error message. What is the problem root cause?

Http failure response for https://mydomain/controller/restui/eum/common/userJourneyUiService/getPathBasedWebUserJourneyTree: 500 OK

Morever, the follwoing error occures in the controller log. You can find the full stack trace of the exception in the attached file.
