There is no scalar implementation for the named 'GraphQLLong' scalar type

I read the docs and did the following:

Gradle:

implementation 'com.graphql-java:graphql-java:15.0' // Also tried v16.1
implementation 'com.graphql-java:graphql-java-extended-scalars:15.0.0'

Java:

import graphql.scalars.ExtendedScalars;
...
newRuntimeWiring()
  .scalar(ExtendedScalars.GraphQLLong)
  .type(...).build();

GraphQL:

scalar GraphQLLong
type Mutation {
  myTest(someValue:GraphQLLong): String
}

And I get the error:

SchemaProblem{errors=[There is no scalar implementation for the named  'GraphQLLong' scalar type]}
graphql.schema.idl.SchemaGenerator.makeExecutableSchema(SchemaGenerator.java:74)
graphql.schema.idl.SchemaGenerator.makeExecutableSchema(SchemaGenerator.java:52)

I notice if I comment out the java lines, it gives me the same error. I verified that the scalar is there via printout of the RuntimeWiring objects getScalars() method.

GraphQLScalarType{name='Long', description='Long type', coercing=graphql.scalars.java.JavaPrimitives$1@5e08b120}

What am I doing wrong?

so if you have:

newRuntimeWiring()
  .scalar(ExtendedScalars.GraphQLLong)
  .type(...).build();

and:

scalar Long
type Mutation {
  myTest(someValue: Long): String
}

you still see the problem?

@UglyHobbitFeet I would close this bug as there is no bug to fix here 😃
