Hi,
Does your InvokeWorkFlow activty for CheckNetworkConnection return false if network connection is failed? Or throw exception?
If former, can you try to put Check True activity after your Invoke WorkFlow file activity.
In both case, can you try set the following Assign in Catch?
But still has a problem… Check True activity will return True if the connection is okay… but how to pass it into Catch block to program understood exception when False ?
