I was advised by LF support to update QF agent to the latest patch. Once I upgraded I am getting this error:

<Errors>

</Errors>
 

I saw that in previous cases such as this, there was a hotfix. Is this what needs to happen?

Also, the job terminates with the error but nothing gets hung up and files processed are being stored in their repo. 

Please advise.
