When i import the same file from TaskManager in Management Portal it is perfectly working and no errors. I need some solution to this problem. i got stuck due to this error. 

This is the error i am getting 

imptask = dbnative.classMethodValue('%SYS.Task','ImportTasks',"F:\\ZBackup\\LISBackupTask.xml","ck")
RuntimeError: server error 1217 <THROW> [ERROR_GENERAL_SERVER]

1. I gave the statement like this and the corresponding error as below –

    imptask = dbnative.classMethodValue('%SYS.Task','ImportTasks',"F:\Zbackup\LISBackupTask.xml","ck")

RuntimeError: server error 1217 <THROW> [ERROR_GENERAL_SERVER]

2. I gave the statement like this and the corresponding error as below –
