I get an error when I try to solve a feasibility problem in JuMP using HiGHS. I use Julia v1.9.1 with the Julia packages JuMP v1.12.0 and HiGHS v1.5.2.
$ julia JuMP_solve.jl
Running HiGHS 1.5.3 [d…

# SciPy callbacks
Associated PR: #19420 (WIP).
Some comments on additions required for `scipy`. In some sense the callbacks in `highs` are [more functional](https://github.com/ERGO-Code/HiGHS/bl…
