Hello,
In OpenLCA 1.7.4 I was using python code via the developer window to update hundreds of values in processes with externally generated values contained in a specially formatted CSV file. With the update to v1.8.0, the code no longer works. What changes need to be made to make this code work in 1.8? Or can someone point me towards the file/directory in the source code on GitHub where I can locate the attributes being called and find the new names? If I knew where to look then I could update this code as needed when new versions of OpenLCA are released, but I haven't been able to locate them as of yet. The original code and the error message are given below.
Thanks,
Ben
