Julia related error in purification.jl code

Question

Hello,
I am getting the following error while running purification.jl, strangely, it is working in REPL "https://replit.com/@scin/EnragedJadedNasm#main.jl". Could you please help me out in this ?

β = 0.00 energy = 0.00000000

What version of Julia are you using? And what version of ITensor. Also from what I can see, the error does not seem to be related to ITensor, because the error message seems to be coming from the SparseArrays package. But it could be coming from ITensor - it's just hard to tell.
