Invoke-WebRequest：远程服务器返回错误：（500）内部服务器错误

Question

Invoke-WebRequest返回无效的操作错误

>powershell Invoke-WebRequest -Uri https://webhook.site/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -Method POST -InFile HappyMeal

以上命令在错误下方返回

Invoke-WebRequest : The remote server returned an error: (500) Internal Server Error.
At line:1 char:1

我该如何解决？
