I have created a macro which will read in a Postcode field. If I use this within a workflow, it works completely fine without error.
I then convert this workflow into an Analytic App, where it simply uses a text box interface so the user can enter a Postcode. The App runs, and spits out the expected output, but also returns an error.
"Missing destination tool."

I have searched the macro for Tool 419 but I cannot find it. I have also searched the xml for this tool with no such luck. Without being able to share my files, does anybody know why this might be occurring? To confirm, it still works through an App in that my output file is as expected, but I don't want this error to appear.
