@apollo/client@4.2.9

Patch Changes

• #13364 2f383e7 Thanks @atharv-sys32! - Fix a bug where GraphQL variable default values were not applied during cache reads when variables with defaults were explicitly set to undefined. This caused @include/@skip directives to throw "Invalid variable referenced" errors when the variable was passed as undefined instead of being omitted entirely.

• #13367 2b39cc8 Thanks @jerelmiller! - Fix an issue where some @export queries would not react to cache updates when the fields keyed by exported variables were updated.
