I updated the test system and a script shows up when creating a ticket

Does anyone have an idea how to fix this? Thank you in advance

I think you need to go into the field configuration for the project and issue type, and find the field description, edit it, and remove the javascript.

Javascript in field descriptions is an old and clumsy hack that is being removed from Jira
