Sapt0 for a open-shell system (uhf) occur error

Hi, developers, I calculate an open-shell system by psi4(Psi4 1.4.1 release) and encountered the following matter after ending CPKS Iterations.

PT2 TERMS:

DFHelper Memory: AOs need 32.523 GiB; user supplied 50.227 GiB. Using in-core AOs.

Traceback (most recent call last):

The most recent 5 function calls were:

psi::DFHelper::get_tensor_(std::_cxx11::basic_string<char, std::char_traits, std::allocator >, double*, unsigned long, unsigned long, unsigned long, unsigned long)
psi::DFHelper::get_tensor
(std::__cxx11::basic_string<char, std::char_traits, std::allocator >, double*, std::pair<unsigned long, unsigned long>, std::pair<unsigned long, unsigned long>, std::pair<unsigned long, unsigned long>)
psi::DFHelper::fill_tensor(std::__cxx11::basic_string<char, std::char_traits, std::allocator >, std::shared_ptrpsi::Matrix, std::vector<unsigned long, std::allocator >)

Printing out the relevant lines from the Psithon → Python processed input file:
core.set_global_option(“BASIS”, “mybs”)
core.set_global_option(“REFERENCE”, “uhf”)
core.set_global_option(“BASIS”, “mybs”)
core.set_global_option(“SCF_TYPE”, “DF”)
core.set_global_option(“FREEZE_CORE”, “True”)
→ energy(‘sapt0’)
