Querying 1 item library

Jump to solution

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

RequestorId: 3f28b335-838a-7221-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.ArgumentNullException: Value cannot be null.

Re: Querying 1 item library

Hi,

Is your query returning that one item into IDCollection variable?

Form error message it looks, the IDCollection is empty, try to log the count of items in that collection?

Use "Collection Operation" action, pass "IDCollection" into it and select "Count". See if it returns 0 or 1.
