Error in executing 1-N mutation

[watanabethais]

I'm having problems in executing a 1-N mutation in my Android project, the service response gives me the following error:

The provided key element does not match the schema (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException)

But the data is successfully added into the DB.

Here is my project schema:

type Inspection @model @key(fields: ["id", "date"]) {
  id: ID!
  name: String!
  date: AWSDate!
  inspectionDetails: [InspectionDetail] @connection(name: "InspectionDetails")
  workDetails: [WorkDetail] @connection(name: "InspectionWorkDetails")
}

type InspectionDetail @model @key(fields: ["id", "itemId"]) {
  id: ID!
  itemId: String!
  inspection: Inspection! @connection(name: "InspectionDetails")
  dateTime: AWSDateTime
  result: String
}

type WorkDetail @model {
  id: ID!
  inspection: Inspection! @connection(name: "InspectionWorkDetails")
  startDateTime: AWSDateTime
  endDateTime: AWSDateTime
}

Checking the log in my project, I've found the following code showing the mutation:

V/PersistentOfflineMutationManager: Thread:[2]:addPersistentMutationObject: Adding mutation[4e71e477-ccc2-4c4a-9279-2e4a11fd0eb4]: CreateWorkDetailMutation

V/AppSyncOfflineMutationManager: Thread:[2]: Added mutation[4e71e477-ccc2-4c4a-9279-2e4a11fd0eb4] to Persistent 

mutation CreateWorkDetail($input: CreateWorkDetailInput!) { 
 createWorkDetail(input: $input) {
  __typename
  id
  inspection { 
	__typename
    id
    name
    date
    inspectionDetails {      
 	  __typename
      nextToken    
    }   
    workDetails {
      __typename
      nextToken
    }
  }
  startDateTime
  endDateTime
 }
}

I've copied the mutation above in the AppSync Queries console to test, and it gives me same error and the data is added in the DB.

{
  "data": {
    "createWorkDetail": null
  },
  "errors": [
    {
      "path": [
        "createWorkDetail",
        "inspection"
      ],
      "data": null,
      "errorType": "DynamoDB:AmazonDynamoDBException",
      "errorInfo": null,
      "locations": [
        {
          "line": 5,
          "column": 3,
          "sourceName": null
        }
      ],
      "message": "The provided key element does not match the schema (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: ValidationException; Request ID: x)"
    }
  ]
}

Removing the "inspection" column in mutation, the error disappears... Maybe am I not modeling the schema correctly?

Hi @watanabethais ,

Thanks for a detailed report. Pinging @awsed to take a look, as it does not appear to be an issue with the SDK.
