Teams Webhook错误:Invoke-RestMethod:泛型传入Webhook接收到错误的负载

Question

我在Powershell脚本中使用已配置的Teams webhook，并不断遇到上述错误消息。奇怪的是，这种配置Webhook的确切方法几个月前在另一个脚本上运行。

以下是我要做的：

#Set URI of the Teams channel Webhook
$URI = 'https:....'
#Define Rest Method Parameters for the Teams Webhook sending
$RestMethodParameters = @{
"URI"         = $URI
"Method"      = 'POST'
"Body"        = $null
"ContentType" = 'application/json'
}
$JSONBody = @{
"@type"      = "MessageCard"
"@context"   = "http://schema.org/extensions"
"themeColor" = '0078D7'
}
#Adding text to title and body
$JSONBody += @{
"title" = "'costReport-func' Function for connecting AzAccount has failed"
"text"  = "Function failed at connection to AzAccount step."
}
#Sending the message to Teams
($RestMethodParameters).Body += ConvertTo-Json $JSONBody
Invoke-RestMethod @RestMethodParameters

有了这个，我得到了"；一般传入的webhook接收到错误的负载"错误消息。是什么导致了这里的问题？
