Error: Returns different types 'Float' and 'Int'

[neha-kherde]

I have a repo for the GraphQL schema which has schema.graphql with the following schema.I am also using dgs-codegen.

type Query {
    GetMetadata(metadataKey: String!): Metadata
}

union Metadata = StringMetadata |
    IntMetadata | FloatMetadata | ObjectMetadata

interface VariabilityEngine_BaseDecision {
    id: String
    name: String
}

type StringMetadata implements BaseDecision {
    id: String
    name: String
    value: String
}

type FloatMetadata implements BaseDecision {
    id: String
    name: String
    value:Float
}

type IntMetadata implements BaseDecision {
    id: String
    name: String
    value: Int
}

From another Java repository I make a graphql call using following code:

GetMetadataProjectionRoot getProjectionRoot = new GetMetadataProjectionRoot();

GetMetadata_StringMetadataProjection stringMetadataProjection =
                getProjectionRoot.onStringMetadata().name().value();
GetMetadata_FloatMetadataProjection floatMetadataProjection =
                getProjectionRoot.onFloatMetadata().name().value();
GetMetadata_IntMetadataProjection intMetadataProjection =
                getProjectionRoot.onIntMetadata().name().value();
       
 GraphQLQueryRequest graphQLQueryRequest = new GraphQLQueryRequest(
                new GetMetadataGraphQLQuery.Builder().metadataKey(metadataKey).build(),
                getProjectionRoot
 );

when making a graphQL call with graphQLQueryRequest, it returns an error
'value' : returns different types 'Float' and 'Int'","locations"

It seems like this is an issue with resolving the type to the correct union type when sending the response - But correct me if I am wrong.

The response is as expected when I mentioned as follows

GraphQLQueryRequest graphQLQueryRequest = new GraphQLQueryRequest(
                new GetMetadataGraphQLQuery.Builder().metadataKey(metadataKey).build(),
                stringMetadataProjection
 );

Any suggestions on what I need to do to fix this error?
