在Python脚本中通过SSM运行时，来自Powershell的意外令牌

Question

我正在通过AWS SSM发送powershell脚本，如下所示：

                                ssm_command_result = ssm.send_command(
                                    InstanceIds=listinst,
                                    DocumentName='AWS-RunPowerShellScript',
                                    Comment='logging the', TimeoutSeconds=600,
                                    DocumentVersion='$DEFAULT',
                                    Parameters={
                                        'commands': [r'function Get-SQLserverKey {\
                                         param ($targets = ".")\
                                         $hklm = 2147483650\
                                         $regPath = "SOFTWARE\Microsoft\Microsoft SQL Server\110\Tools\Setup"\
                                         $regValue1 = "DigitalProductId"\
                                         $regValue2 = "PatchLevel"\
                                         For ($i = 24; $i -ge 0; $i--) {\
                                         $k = 0\
                                         For ($j = 14; $j -ge 0; $j--) {\
                                         $k = $k * 256 -bxor $binArray[$j]\
                                         $binArray[$j] = [math]::truncate($k / 24)\
                                         $k = $k % 24\
                                         }\
                                         $productKey = $charsArray[$k] + $productKey\
                                         If (($i % 5 -eq 0) -and ($i -ne 0)) {\
                                         $productKey = "-" + $productKey\
                                         }\
                                         }\
                                         $win32os = Get-WmiObject Win32_OperatingSystem -computer $target\
                                         $obj = New-Object Object\
                                         $obj | Add-Member Noteproperty Computer -value $target\
                                         $obj | Add-Member Noteproperty OSCaption -value $win32os.Caption\
                                         $obj | Add-Member Noteproperty OSArch -value $win32os.OSArchitecture\
                                         $obj | Add-Member Noteproperty SQLver -value $SQLver\
                                         $obj | Add-Member Noteproperty SQLedition -value $SQLedition\
                                         $obj | Add-Member Noteproperty ProductKey -value $productkey\
                                         $obj\
                                         }\
                                         }\
                                         Get-SQLserverKey'
                                        ]
                                    })

powershell将返回以下错误：

我已经删除了所有可能的退格，但都是徒劳的。谢谢你的建议。谢谢 问候
