Describe the bug

I am trying to compose a subgraph into a fusion .fsp file with the following schema:

type Author {
    id: ID!
    reviews: ReviewConnection
}

type Book {
    id: ID!
    reviews: ReviewConnection
}

input CreateReviewInput {
    bookId: ID!
    reviewerId: ID!
    authorId: ID!
    comment: String!
    rating: Int!
}

input DeleteReviewInput {
    id: ID!
}

type Review {
    id: ID!
    bookId: ID!
    reviewerId: ID!
    authorId: ID!
    comment: String!
    rating: Int!
}

type ReviewConnection {
    items: [Review]
    nextToken: String
}


type Mutation {
    createReview(input: CreateReviewInput!): Review
    deleteReview(input: DeleteReviewInput!): Review
}

type Query {
    getReview(id: ID!): Review
    listReviews(limit: Int, nextToken: String): ReviewConnection
    queryReviewsByBook(bookId: ID!, limit: int, nextToken: String): ReviewConnection
    queryReviewsByReviewer(reviewerId: ID!, limit: int, nextToken: String): ReviewConnection
    queryReviewsByAuthor(authorId: ID!, limit: int, nextToken: String): ReviewConnection
}

schema {
    query: Query,
    mutation: Mutation
}

The config file is like the following:

{
    "subgraph": "reviews",
    "http": { "baseAddress": "https://<some-endpoint>/graphql" }
}

I am able to successfully pack the subgraph into reviews.fsp file. However, I am getting the following error when trying to compose the gateway fsp file:

% dotnet fusion compose -p ./fusion-gateway/gateway.fgp -s ./lib/sourceApis/ReviewsService

Unhandled exception: System.InvalidCastException: Unable to cast object of type 'HotChocolate.Skimmed.MissingType' to type 'HotChocolate.Skimmed.ScalarType'.

Any idea what I am doing wrong?

Steps to reproduce

1. Create a folder with above schema file and subgraph config.
2. dotnet tool restore (Note, I am using HotChocolate.Fusion.CommandLine version 13.6.0-preview.2)
3. dotnet fusion subgraph pack -w ./lib/sourceApis/ReviewsService
4. dotnet fusion compose -p ./fusion-gateway/gateway.fgp -s ./appsync-infrastructure/lib/sourceApis/ReviewsService

Relevant log output

No response

Additional Context?

The issue was a typo, input argument was int rather than Int :)

Was at a conference in Copenhagen and could not answer... yes ... for 13.6 we are focusing on the validation story to have better errors.
