.Net中使用Fast Endpoints时集成测试环境报错排查

业务项目里FastEndpoints组件运行完全正常，但在集成测试环境启动时直接失败，报错触发在Program.cs的builder.Services.AddFastEndpoints代码行，报错信息见附图。

我怀疑是程序集版本不一致导致的问题，但没法确定，希望有人帮忙排查原因。

以下是我的OrderApiApplicationFactory类代码：

public class OrderApiApplicationFactory<TEntryPoint> : WebApplicationFactory<Program>, IAsyncLifetime where TEntryPoint : Program
{
    private const string Database = "master";
    private const string Username = "sa";
    private const string Password = "yourStrong(!)Password";
    private string _connectionString;
    private const ushort MsSqlPort = 1433;
    private const ushort RabbitMqPort = 5672; 
    private readonly MsSqlContainer _mssqlContainer;
    private readonly RabbitMqContainer _rabbitMqContainer;

    public HttpClient HttpClient { get; private set; } = default!;

    private const string RabbitMqUsername = "guest";
    private const string RabbitMqPassword = "guest";

    public OrderApiApplicationFactory()
    {
        _mssqlContainer = new MsSqlBuilder()
            .WithImage("mcr.microsoft.com/mssql/server:2022-latest")
            // Remove static port binding and let Docker assign random ports
            .WithPortBinding(0, MsSqlPort)
            .WithEnvironment("ACCEPT_EULA", "Y") 
            .WithEnvironment("SA_PASSWORD", Password)
            .WithWaitStrategy(Wait.ForUnixContainer().UntilPortIsAvailable(MsSqlPort))
            .Build();

        _rabbitMqContainer = new RabbitMqBuilder()
            .WithImage("rabbitmq:3-management-alpine") 
            .WithPortBinding(5672, RabbitMqPort) // Bind RabbitMQ's default port to the specified host port
            .WithEnvironment("RABBITMQ_DEFAULT_USER", RabbitMqUsername)
            .WithEnvironment("RABBITMQ_DEFAULT_PASS", RabbitMqPassword)
            .WithWaitStrategy(Wait.ForUnixContainer()
                .UntilPortIsAvailable(RabbitMqPort) // Wait until the specified host port is available
