nuwave/lighthouse: Undefined index: id

Question

I'm observing wierd behaviour with @json directive. I have an laravel application and Graphql calls are handled using nuwave/lighthouse. I have user table and one of the column in this table is json data which stores user hobbies in different language.

to be more precise:

column name: language_mapping
type: json
data structure: { hobbies : { en: "", de: "", da: ""}}

What is working?

Below update query works well and updates only specic language under hobbies.

GraphQL mutation:

mutation {  updateLanguageSpecificUsers(user_id: 33, language_mapping: "hobbies.en=singing") {    
    language_mapping {      
        hobbies {        
            en          
        }          
    }     
}
}

I understood that this line @json(columns: ["language_mapping"], model: Users) is responsible for updating the right key with the value.

Users.graphql file

extend type Mutation {
  updateLanguageSpecificUsers(
    language_mapping: Mixed
    user_id: Int @rules(apply: ["numeric"])
  ): Users @json(columns: ["language_mapping"], model: Users) @update
}

What is not working?

I want to create an record if record not present else update the record if its present so, I created one more mutation for create or update but when I run the query, I'm getting "debugMessage": "Undefined index: id", "file": "/var/www/dummy/api/app/GraphQL/Directives/JsonDirective.php",

mutation { 
  updateOrCreateLanguageSpecificUsers(language_mapping: "hobbies.en=singing", user_id: 4171){
     language_mapping {      
        hobbies {        
            en          
        }          
    }      
  }
}

Users.graphql file

extend type Mutation {
  updateOrCreateLanguageSpecificUsers(
    language_mapping: Mixed
    user_id: Int @rules(apply: ["numeric"])
  ): Users @json(columns: ["language_mapping"], model: Users) @updateOrCreate(search: ["user_id"])
)

I couldn't understand whats going wrong in this mutation.

I would like to update or create based on presence of data.
