Problem with SAPT calculation

Hello, all. My SAPT calculation is wrong, but I don’t know how to modify it. I hope you can help and give me some suggestions. Thank you.
molecule dimer {
0 1
( * Cartesian coordinates for the first molecule)

-1 1
( * Cartesian coordinates for the first molecule)
}
set {
basis aug-cc-pVTZ
guess sad
scf_type DF
freeze_core True
}

energy(‘sapt2+(3)dmp2’)

RuntimeError:

The most recent 5 function calls were:

Printing out the relevant lines from the Psithon → Python processed input file:

How many atoms and how many basis functions for the dimer?

Hello friend,
I am very happy to receive your reply. I found that the problem was caused by the molecular construction of ultraedit. It has been solved now. Thank you very much.
