Encountering a 403 Forbidden error while working on a diagram in Visual Studio Code

Question

I think the syntax is fine, it just seems to happen when I add too many lines/elements.

Is there a way around this?

PS: I'm a business user/novice so if there's a tutorial to follow, please link it.

Answer 1

Do you use the PlantUML extension? Please, show the code of your diagram.
