WSO2 ESB：SFTP文件传输：验证失败

Question

我是WSO2的新手。我试图将带有传输vfs模块的文件从本地（Windows）移动到sftp服务器。我可以通过此代理服务获得预期的结果

SELECT DISTINCT PhoneNumber
FROM User
where  (len(PhoneNumber) = 13 or len(PhoneNumber) = 10 or phoneNumber like '311%' or phoneNumber like '00311%' )

然后，我继续在服务器（Ubuntu）上尝试此操作。但是我遇到“验证失败”错误。这是代码

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
    name="SFTPProxy"
    transports="vfs"

            </log>
        </inSequence>
        <outSequence/>
        <faultSequence/>

    <parameter name="transport.vfs.MoveAfterProcess">vfs:sftp://****@*******</parameter>
    <parameter name="transport.vfs.SFTPIdentityPassPhrase">****</parameter>
</proxy>

这是异常堆栈。请引导我。
