hello, I also met this problem using the version 1.4.
Not sure if it is the problem of computer, my model is too big with more than 2000 rooms,(it runs normally with 1000rooms), the osm is running normally for 2hours and suddenly terminated, the file is existing within the address but the size is much smaller, and the HB Read Room Energy Result component report this problem: Solution exception:index out of range: 0
It sounds like you might have run out of memory when trying to parse in all of this data. Are you still able to get things like the EUI using the HB End Use Intensity component? If so, then it’s probably too much data to be parsed into Grasshopper. I would try requesting data on a monthly basis instead of hourly. Or you can use the HB Read Custom Result component to import data one collection at a time.
