InvalidSyntaxError while runnig spring boot app based on graphql-dgs-spring-boot-starter

Hi, I faced with the following issue:

InvalidSyntaxError while runnig spring boot app based on graphql-dgs-spring-boot-starter

Below are some details/expectations.

Expected behavior:

Application is up and running with successfully generated classes from defined schema

---

Actual behavior:

Application is failing on startup with not meaningful error message

---

Steps to reproduce:

• I'm a using graphql-dgs-platform-dependencies:6.0.1 with spring-boot 3.+ (3.05), java 17 and code generation plugin ('com.netflix.dgs.codegen' version "5.7.0") for home examples.
• Code generation is passed successfully application is failed at startup with the following unclear error:

There are problems with the GraphQL Schema:
	 * InvalidSyntaxError{ message=Invalid Syntax : offending token '"name"' at line 2 column 3 ,offendingToken="name" ,locations=[SourceLocation{line=2, column=3}] ,sourcePreview={
  "name": "Untitled GraphQL Schema",
  "schemaPath": "schema.graphql",
  "extensions": {
    "endpoints": {
}

---

Absolutely same schema is working fine with spring-boot-starter-graphql based spring boot app v3.0.5 and java 17 (there is only difference in graphql-java version - 19.5 vs 19.3 in spring-boot-starter-graphql) with hand written classes corresponding to schema types.
To my mind if schema is incorrect code generation should fail, isn't it?

Here is schema:

type Query {
    category(id: String): Category
    categoryByName(name: String): Category
    categories: [Category]
    recipe(id: String): Recipe
    recipes: [Recipe]
}

type Mutation {
    addRecipe(description: String): Recipe
    addRecipeWithPayload(recipeDto: RecipeDto): Recipe
    addCategory(name: String): Category
}

type Category {
    id: ID
    name: String
    recipes: [Recipe]
}

type Recipe {
    id: ID
    description: String
    prepTime: Int
    cookTime: Int
    servings: Int
    source: String
    url: String
    notes: String
    difficulty: Difficulty
    category: Category
}

input RecipeDto {
    description: String
    prepTime: Int
    cookTime: Int
    servings: Int
    source: String
    url: String
    notes: String
    difficulty: Difficulty
    categoryId: String
}

enum Difficulty {
    EASY, MODERATE, KIND_OF_HARD, HARD
}
