Terrain-Correction operator error #19

can you save the graphs with snapista and with the GUI and post them here? |

Sure, here are the graphs, only the Terrain-Correction node (don't worry about differences in map projection). Generated with Snap 8.0.0 GUI: <graph id="Graph">

Hi,
the Terrain-Correction operator is not working properly. One thing is a non-existent element in the Graph leading to
However, when removing element
outputComplexfrom the graph (I exported it into a file and run withgpt) the next error occurs which I did not further investigate:When I re-create the workflow with SNAP GUI it runs fine. So, I guess there is a version conflict when building the graph as elements of the operator seem to be outdated? I'm using snapista version 0.2.0 and snap version 8.0.0 with Python 3.7 installed with conda from terradue repo.
