FDDB114: Invalid major version error

Field	Value
Code	FDDB114
Severity	Error

Message

FluentDynamoDbSchemaVersion major version must be at least 1, but was {0}.

Description

The major component of the schema version must be at least 1. A major version of 0 or negative is not a valid schema version. When this error is emitted, all code generation is halted — no entity sources will be produced.

This typically occurs when the attribute is constructed with invalid literal values, or when IL manipulation bypasses the attribute constructor's runtime validation.

Example

The following code triggers this diagnostic:

using Oproto.FluentDynamoDb.Attributes;

// Major version 0 is invalid — must be at least 1
[assembly: FluentDynamoDbSchemaVersion(0, 0)]

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

Fix

Provide a valid major version (1 or higher):

using Oproto.FluentDynamoDb.Attributes;

[assembly: FluentDynamoDbSchemaVersion(1, 0)]
