Zephyr integration in Jira - Err 500 when i click on create a test

my team and i recently made a request to go on trial version with zephyr for a month to evaluate the tool and eventually by a company licence. Now Zephyr has been integrated in our teams Jira and the trial is started, but when i want to try zephyr an click on «create a test», there's an error 500 and nothing's going on. can we have someone from smartbear support to look at this for us?
