Help interpreting an error with exponentials using JuMP variables

Sorry, I just didn’t include the full expression of the objective to try to minimize the code. I have fixed the order of the @variable statements. I have another thread where I have posted my updated code with a new problem help-creating-a-jump-variable-array So I won’t repost it here to reduce redundancy, however I can eventually post my full minimization expression if my problems aren’t worked out my other post. Thank you for your help!
