Hi @wubneh , thanks for posting. Your logfile attachment did not seem to come through. Could you try again please?

Also, you might find useful solutions in some other threads on this forum that deal with KeyErrors in NDR:

Hi @wubneh ,

The log file reads, “KeyError: 0”. This likely indicates that you have a value in the LULC raster of 0 that is not represented in the biophysical table. Please check and adjust that input.

Agreed. Also if you try updating to a more recent version of invest, I believe you might get a more helpful error message in this instance. InVEST | Natural Capital Project

Thank you for your response. Yeah, I got this error and corrected and the KeyError comes again with another number i.e. 10 and on another step 7. I still need your help.

Hi @wubneh,

Every value in the LULC needs to have a corresponding value in the biophysical table. You need to either include ALL of the values mentioned by such errors in your biophysical table or to remove them from the LULC. Does that make sense?
