I just had this problem while running an SP2013 JSOM asynch function
我在运行 SP2013 JSOM 异步函数时遇到了这个问题
clientContext.executeQueryAsync(Function.createDelegate(this, OnQuerySuccess), Function.createDelegate(this, OnQueryFail));
and solved it via IIS reset.
并通过 IIS 重置解决了它。
Just open Windows PowerShell as Administrator and run iisreset.
只需以管理员身份打开 Windows PowerShell 并运行iisreset.
