Hello, I found this error when I used the data of the model to calculate the coastal vulnerability. What is the reason?

Hi @XMW ,

Thanks for writing in and for attaching your log file.

It appears this could be an issue with your drive permissions. Do you have write access to “F:” drive? Is it possible that this drive is cloud based instead of local? I see that all your inputs are called from “E:/”, not from “F:”. It also seems odd that the slash is opposite.

Please check the drive permissions.

-Jesse

Thank you for your reply. I suspected it before, so I tried to put them in the same drive E , but the same problem occurred.

Hi @XMW ,

I was able to run the model successfully on my end with the same input sample data files that you used. This leads me to believe that there is a permissions issue with saving to your drives, or perhaps limited space.

I do suggest downloading the newest version of InVEST, currently [3.9.2](https://naturalcapitalproject.stanford.edu/software/invest), and attempting the same run with that. Additionally, while I was able to run the model with the `.dbf` files, just as you did, we usually recommend inputting the `.shp` vectors instead. Please give that a try as well.
