DYNDB024: Missing required attribute

Field	Value
Code	DYNDB024
Severity	Error

Message

Property '{0}' in entity '{1}' is missing required attribute '{2}'

Description

Properties used in DynamoDB operations must have appropriate attributes defined. The source generator requires specific attribute combinations for correct code generation of mapping, serialization, and key handling.

Example

The following code triggers this diagnostic:

[DynamoDbTable("Orders")]
public partial class Order
{
    [PartitionKey]
    [DynamoDbAttribute("pk")]
    public string Pk { get; set; } = string.Empty;

    [DynamoDbMap]
    public Address ShippingAddress { get; set; } = new();
}

Fix

The corrected version:

[DynamoDbTable("Orders")]
public partial class Order
{
    [PartitionKey]
    [DynamoDbAttribute("pk")]
    public string Pk { get; set; } = string.Empty;

    [DynamoDbMap]
    [DynamoDbAttribute("shippingAddress")]
    public Address ShippingAddress { get; set; } = new();
}
