GraphQL - variable not defined by operation

Question

My GraphQL schema is defined as:

type Query {
    getEntity(id: Int!): Entity
    getEntityUsers(entityId: Int!, statusId: Int): [User]
}

type Entity {
             


        

Answer 1

Every operation (query or mutation) must explicitly define any variables you use inside that operation. So if you have a variable called $statusId, the type for this variable must be specified as part of your operation definition:

query getEntity($id: Int!, $statusId: Int) {
  # your selection set here
}

Where those variables are used within your query (whether at the root level, or elsewhere) is irrelevant -- they must always be defined as part of your operation definition.
