Hi,
I am running this graph and I am facing the following error message after the process has started. At some point it claims:
Error : [NodeId: Subset] null
Not sure how to interpret this error. I am doing a basic processing of S3 OLCI data. The only modification I have done to the original graph created in the Graph Builder is to change the source product to a variable ($input1) and the output to another variable ($target1) which are later call in GPT
Any idea on this?
