GraphQL - Mutations

Given the input type:

input ProductInput { name: String!, price: Float }

and mutation:

mutation addProduct($product: ProductInput!) { createProduct(input: $product) { id name } }

What happens if you call this mutation with { "product": { "price": 10.5 } }?

AMutation fails due to missing required 'name' field

BMutation succeeds and creates product with null name

CMutation succeeds and ignores missing 'name' field

DMutation fails due to invalid price type

Step-by-Step Solution

Final Answer:

Quick Check:
