S1TBX batch processing

Hi everyone,
I have to process quite a huge amount of interferograms (Sentinel 1 images) but I’m facing some problems using the batch processing tool in SNAP.
I could properly set the batch but it only works with the first “.stack” product. After it I get this error:

I need to save the phase, coherence and intensity as final output. How can I do?
I can’t figure out where I’m wrong…

Thak you a lot for your precious help.
