Today I am dealing with a did_imputation from Kirill, 2021, and I found the error "command ms_get_version is unrecognized" after running the code

Code:
did_imputation Y i t ei,autosample fe( TYPE2 yr) controls($controllist) maxit(30000) tol(0.001)
Could you please point out what is the problem and what I should do to solve it?
