I downloaded openLCA few days ago (version 1.7) and used the PET bottle case study (even if for 1.5 version) to understand how to create my own case of study (quite similar to the case study of PET bottle). Till yesterday everything was ok. Since yesterday evening I got this error message:
Failed to create save RootEntity
I follow the same instructions of the PET case study (that till yesterday were working and giving same results of the online example):
1) I create a child category in the flows folder
2) I create flows giving them reference quantities and specifying that are products
3) I create a child category in the process folder (with the same name of the one in the flows folder)
4) I try to create the new process in this folder selecting the reference quantity from the flow and I do not succeed since I got the above mentioned error message.
What could it be?
