Batch processing INSAR error? - [NodeID: Read(2)] 'file' parameter must be set

I’m having an issue batch processing S1 data using the given XML scripts included with SNAP. I saw a a previous discussion that mentioned this issue (Batch processing read file error), and I noticed that the XML for this official script has been modified to rectify the error.

However, I am still not able to get it running. Any suggestions? I’m running SNAP desktop on a Windows box. I can manually run through the chain with success.

The graph has two readers. The batch processing can only handle one.
