#7747 ddce036e1 Thanks @trevor-scheer! - The minimum version of graphql officially supported by Apollo Server 4 as a peer dependency, v16.6.0, contains a serious bug that can crash your Node server. This bug is fixed in the immediate next version, graphql@16.7.0, and we strongly encourage you to upgrade your installation of graphql to at least v16.7.0 to avoid this bug. (For backwards compatibility reasons, we cannot change Apollo Server 4's minimum peer dependency, but will change it when we release Apollo Server 5.)
Apollo Server 4 contained a particular line of code that makes triggering this crashing bug much more likely. This line was already removed in Apollo Server v3.8.2 (see #6398) but the fix was accidentally not included in Apollo Server 4. We are now including this change in Apollo Server 4, which will reduce the likelihood of hitting this crashing bug for users of graphql v16.6.0. That said, taking this @apollo/server upgrade does not prevent this bug from being triggered in other ways, and the real fix to this crashing bug is to upgrade graphql.
