Do not present some Microsoft generic error like: An error occurred on the server when processing the URL. Please contact the system administrator.

But instead, have a Custom Jira align error describing what happened or a guardrails scenario that blocks the user to add so many items in one single state column

Workaround

Filter / refine the Tier 1 filter in order to show fewer work items in the Kanban hence not exceeding the buffer limit
