Compiler gives the following error while executing the Losless Convexification Section:

I'm new to Julia using version 1.8.5 and JuMP version is v1.10.0. Need help in this regard. Thanks

I have resolved this issue by changing the Model=(ECOS.Optimizer) "with_optimizer" is not a valid syntax anymore!
