Error processing template after execution for parameter: 'postExecuteTemplate'

Dear all,

I installed sen2cor, now I can use it by entering Optical\Thematic Land Processing or Using Graph Builder to build a graph and run it.
The problem is when I saved the graph as myGraph.xml. And use gpt myGraph.xml. It gives me an error:
Error: [NodeId: Sen2Cor] Error processing template after execution for parameter: ‘postExecuteTemplate’

I used the default value for this parameter, it works in GUI. Can anyone help me with this? Thank you very much!

Hi, I am getting the same error, is this issue resolved?

First, install Sen2Cor plugin in SNAP GUI.
Second, run Sen2Cor plugin and follow guide in SNAP GUI.
Then SNAP GUI will install Sen2Cor bundle.
After installing, you can use Sen2Cor in python snappy.
