Laravel lighthouse inject nested mutations

Question

Here are my inputs for nested mutation:

input ActivityInput {
  id: ID
  user_id: ID
  goal: String
}

input ActivityRelationInput {
  upsert: [ActivityInput]
  delete: [ID]
}

input CustomerInput {
  id: ID
  name: String
  activities: ActivityRelationInput
}

And here is my mutation:

extend type Mutation {
  customerUpsert(input: CustomerInput! @spread): Customer
  @upsert(model: "App\\Models\\Customer")
  @inject(context: "user.id" name: "activities.upsert[].user_id")
}

I need to inject user.id into Activity input, but don't know how to use @inject for array inputs. I've tried the code above but didn't succeed. How can I achieve my goal?

Not a solution for your problem, but it could be a workaround:

I was facing a similar problem. To write a Chat-Message the user updates the Chat by adding a new Message and i want to inject the user.id from context as author_id.

Using lighthouse @nest directive did the job for me.

updateChat(id: ID! @eq input: ChatOperations @nest): Chat @update @inject(context: "user.id" name:"input.newMessage.author_id")

The Chat operations input:

inputChatOperations {
    newMessage: CreateMessageInput @create(relation: "messages")
}
