What happened?

We have a user who added 2 pages of the quick links, and then she got an error. Below is the error message from the dev console
"{"code":"BadRequest","message":"Maximum size supported for each extension is : 2 KB.","innerError":{"date":"2026-03-18T01:28:28","request-id":"6d2b35e0-e77c-4a17-919b-465d0027ef64","client-request-id":"427c641c-3621-26d2-2c42-600b24e8e165"}}"
