PixEx in gpt

Is it possible to use Export Pixels operator as a node of a gpt graph?

My ideal graph is: Read -> (Resample?) -> BandSelect -> PixEx resample_and_select_extract.xml (2.3 KB)
When I load this graph SNAP complains that “no converted defined for value ‘coordinates’” and later “No coordinates specified”.

I found a similar question Batch processing using GPT, Export Pixels (PixEx) but changing sourceProducts to sourceProduct did not help.
