C# PuppeterSharp.EvaluationFailedException:执行上下文被破坏，很可能是因为导航错误

使用PuppeterSharp 3.0.0和.net core 5.0

以下代码在从c#运行时引发异常。在浏览器控制台中运行相同的脚本也可以。我们做错了什么？ 这是页面：

代码：

例外情况：

 PuppeteerSharp.EvaluationFailedException: Execution context was destroyed, most likely because of a navigation. ---> PuppeteerSharp.MessageException: Execution context was destroyed, most likely because of a navigation. at PuppeteerSharp.CDPSession.SendAsync(String method, Object args, Boolean waitForCallback) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\CDPSession.cs:line 157 at PuppeteerSharp.CDPSession.SendAsync[T](String method, Object args) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\CDPSession.cs:line 109 at PuppeteerSharp.ExecutionContext.ExecuteEvaluationAsync(String method, Object args) in C:\projects\puppeteer-sharp\lib\PuppeteerSharp\ExecutionContext.cs:line 182 --- End of inner exception stack trace ---

您为我编写的代码没有wait页面。waitForNavigationSync（）刚刚重试，请尝试{var elem=wait WebPage.EvaluateExpressionAsync（js）；return true；}catch（异常ex）{Console.Write（ex）；返回false；}
