Hi, I’m now writing my codes and encountered a really strange error: [image] As can be seen, the error said “obj_path_tmp not defined”. However, in debugging mode (using Debugger), I can read the value (even add to obj_linearised): [image] So, what’s wrong with it? It’s really confusing … EDI…

The debugger handles scope slightly wrong when you execute julia code in it, so if you defined obj_path_tmp in a more inner scope it is possible the debugger is showing it still being defined while it is not. Here is a MWE: 1|debug> st In f() at REPL[11]:1 1 function f() 2 for i in 1:5 3 …

Please don’t post screenshots (copy should work from most IDEs and the terminal), and make an MWE.
