GraphQL Improvements

We introduced a new error response for queries that exceeded 2MB size to provide greater visibility into failing queries. Previously, queries over 2 MB would either return `HTTP 460 Client closed connection` prematurely after an extended period of time or timeout on the customer side. Now, requests over `2MB` will return an `HTTP 413 Request Entity Too Large` response. You can find more information about GraphQL error responses on the Limits page.
