Have you followed Linux, MacOs kernel configuration steps to increase Maximum open files and Maximum virtual memory areas limit?
- Yes, I have
Additional context
The browser's developer tools confirms the query is sent as a query string parameter, which introduces a hard limitation on the request size. Changing to a POST request and sending it in the body usually greatly increases the limit.
