traccar: Showing reports-> trips does not load

Hi,

I updated traccar today from 4.14 to the latest release. Every reports works fine except trips. (it does before updating, nothing changed in config) If there are no data for the device this report “works”. If there is some data, it show three grey bars (loading indicator) and nothing happens. There is no error in the logs. After some time (timeout) it displays a message on the browser:

{ "servlet":"org.glassfish.jersey.servlet.ServletContainer-1d6713dd", "message":"Service Unavailable", "url":"/api/reports/trips", "status":"503" }

When I directly call the api /api/reports/trips in GET with correct data (incorrect data gives error), it runs into timeout.
