DYNDB030: Invalid attribute name

Field	Value
Code	DYNDB030
Severity	Error

Message

Attribute name '{0}' on property '{1}' is invalid: {2}

Description

DynamoDB attribute names must follow naming conventions and cannot contain certain characters. Attribute names must be between 1 and 255 characters long and should not begin with a number when used in expressions.

Example

The following code triggers this diagnostic:

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

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

Fix

The corrected version:

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

    [DynamoDbAttribute("orderStatus")]
    public string Status { get; set; } = string.Empty;
}
