📝 Description
We made the
FunctionDataFetcher
return nullable in this change #613. That is a good change but I only realized after integrating into our internal SDK that this also impacts theKotlinDataFetcherFactoryProvider
.KotlinDataFetcherFactoryProvider
returns aDataFetcherFactory
, and in graphql-java those are supposed to implement the same types that theDataFetcher
returns. So this change fixed that to match the same types in graphql-java.This is a breaking change as the interface signature has now been changed.
