Able to use non input type as input type when wrapped in GraphQLList #2656
Description
Describe the bug
The issue occurs when using GraphQLArgument builder with type as GraphQLList(an instance of GraphQLInputType) and wraps a non-input type like GraphQLObjectType.
Was also able to build a schema as shown in the following code.
To Reproduce
GraphQLObjectType graphQLObjectType = GraphQLObjectType.newObject().name("ObjectTypeA").build();
GraphQLArgument argument = GraphQLArgument.newArgument()
.name("testArg")
.type(GraphQLList.list(graphQLObjectType))
.build();
GraphQLObjectType queryObject = GraphQLObjectType.newObject()
.name("Query")
.field(GraphQLFieldDefinition.newFieldDefinition()
.name("testField")
.argument(argument)
.type(graphQLObjectType)
.build())
.build();
GraphQLSchema schema = GraphQLSchema.newSchema()
.query(queryObject)
.additionalTypes(Collections.emptySet())
.additionalDirectives(Collections.emptySet())
.build();
