Hello, I moved my software projects from an old instance of jira cloud to a newer one. I made it by the help of jira customer care that moved my projects on behalf of me (backup/restore).
In the new instance I can see every projects, I can move issues in the board for every project. For many of them, not all, I (administrator) cannot add new issues, and neither do other users. I got "internal server error" toast message and a 500 error in the js console.
What's happening? thank you for helping me, I'm stuck with my work
