404错误

运行子程序(在Zotero中直接运行JavaScript代码)失败。解析表达式出错。
内部错误：响应状态代码不指示成功: 404 (Not Found)。
原始表达式：
//using System.Net.Http.Headers;
var client = new HttpClient();
var content = new StringContent({jscode});
content.Headers.ContentType = new MediaTypeHeaderValue("application/javascript");
var request = new HttpRequestMessage()
{
    Method = HttpMethod.Post,
    RequestUri = new Uri($"http://127.0.0.1:23119/debug-bridge/execute?password={{Password}.UrlEncode()}"),
    Content = content
};
using (var response = await client.SendAsync(request))
{
    response.EnsureSuccessStatusCode();
    var body = await response.Content.ReadAsStringAsync();
    return body;
}(赋值)
