DYNDB007: Missing DynamoDbAttribute

Field	Value
Code	DYNDB007
Severity	Error

Message

Property '{0}' has DynamoDB key attributes but is missing [DynamoDbAttribute]

Description

Properties with DynamoDB key attributes must also have [DynamoDbAttribute] to specify the attribute name. The source generator needs the DynamoDB attribute name to generate correct key handling code and map properties to DynamoDB item attributes.

Example

The following code triggers this diagnostic:

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

    [SortKey]
    [DynamoDbAttribute("sk")]
    public string Sk { get; set; } = string.Empty;
}

Fix

The corrected version:

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

    [SortKey]
    [DynamoDbAttribute("sk")]
    public string Sk { get; set; } = string.Empty;
}
