Blazor Server(.NET7)启动报错：连接关闭且电路主机未初始化

现象描述 #

• 启动应用后，浏览器立即进入“重连”模式，控制台抛出错误：

Uncaught (in promise) Error: Server returned an error on close: Connection closed with an error.
at Ft._processIncomingData (blazor.server.js:1:73086)
at Ft.connection.onreceive (blazor.server.js:1:67009)
at i.onmessage (blazor.server.js:1:51322)

• 后续每隔20秒重复出现日志：

Error: Error: Circuit host not initialized.

• 应用启动日志仅显示身份认证相关提示，无其他异常：

Cookies was not authenticated. Failure message: Ticket expired

调试尝试 #

自定义实现CircuitHandler派生类CircuitHandlerService，在OnCircuitOpenedAsync方法中设置断点，但既未捕获到错误，也未触发该事件，不确定实现是否正确。代码如下：

public class CircuitHandlerService : CircuitHandler
{
    /// <summary>
    /// Singleton
    /// </summary>
    private readonly ICircuitUserService circuitUserService;

    public string CircuitId { get; private set; }

    public CircuitHandlerService(
        ICircuitUserService circuitUserService)
    {
        this.circuitUserService = circuitUserService;
    }

    public override Task OnCircuitOpenedAsync(Circuit circuit, CancellationToken cancellationToken)
    {
        CircuitId = circuit.Id;
        return base.OnCircuitOpenedAsync(circuit, cancellationToken);
    }

    public override Task OnCircuitClosedAsync(Circuit circuit, CancellationToken cancellationToken)
    {
        circuitUserService.Disconnect(circuit.Id);
        return base.OnCircuitClosedAsync(circuit, cancellationToken);
    }
}
