Querying 1 item library

Hi,

 

I am querying library with 1 item and storing in to a 'IDCollection'. Then using for-each to run through the IDCollection (1 item and getting it's document ID)

 

On for-each loop, I am doing 'For each IDcollection', out put to 'IDVar'

When I reach the for-each loop, my workflow is crashing with the following error. (The workflow is going in to the for-each then outputting a blank line as the IDVar) I am assuming the 1-item is the culprit. How can I overcome this? Any help is appreciated!

 

I tried changing gathering Document ID in to IDs...did not help either
