I think that is what you need. I also just noticed that in the error you copied, the path to that folder seems to contain some very unusual characters, so maybe that could also be a problem. Try to include the jkfit basis first, i.e. make sure it is in your Psi4 basis path and add the appropriate keyword to your input file (I can’t remember what it is but it should be in the manual).
If that still gives you the above error, consider changing your path so that it only contains standard ASCII characters to make sure Psi4 can recognize it properly.
