Integration with Jira Cloud instance problem

I’ve been trying to connect our Jira and Shotgun instances and stumbled on an error that I do not actually understand why happens.
In my Jira Cloud instance I have ‘Task’ issue type.
Any ideas how to fix this?

EDIT: this error happens when creating task on a test project through shotgun website.

CRITICAL:plugin.sg_jira_event_trigger.process_event:An error occured processing an event.
