Data not getting loaded

We have a got a flow service which gets a file from location and loads it in the database table.
But the service is not loading the file and showing the below exception:

" com.wm.lang.flow.FlowException No DATa loaded "
The load service is given inside a sequence step which is child of branch step.

Please help me in the above mentioned issue.

Thanks in advance

With that information it’s impossible to know.

From Developer execute your flow step by step until you reach the point where it fails, IE while running service pub.file:getFile, then look for errors on server.log.
