We use spring-graphql (v1.1.3) alongside federation-graphql-java-support. After upgrading the latter to 3.0.1 we have started getting the following exception:
java.lang.AbstractMethodError: Receiver class com.apollographql.federation.graphqljava._Any$1 does not define or inherit an implementation of the resolved method 'abstract java.lang.Object parseValue(java.lang.Object)' of interface graphql.schema.Coercing.
Unfortunately I am not able to share our code, but our federation code looks very much like the example in the docs here - GitHub - apollographql/federation-jvm: JVM support for Apollo federation
Any help would be greatly appreciated.
