How can I kill this error msg

[tjgh1322]

When I use "SFTP : Remote to Local" this thing occurs

Of course, there is no problem with the function... But everyday my companies ask me about this things and I always say 'Ignore it'
But I want to solve it

and the error.log is like this

There could be multiple reasons :

1. It's a temp file that is not available anymore when sftp try to mull it on your local.
2. It's a bug related to the rights on the file (or parent folder).
3. The file simply doesn't exist.
