> If I'm in Java, JavaScript, or Python and there is a code fault, the system provides me a stack trace of the call structure that lead to the error. If I catch the error I can output more related data as I deem necessary. This comes effectively, out of the box.

Sure, if you are not writing a program using event-driven async style. Every monolith I've worked with has been in async style pretty much.

With global state in the monolith, this can become quite difficult to reason about. By contrast, with microservices, you can analyze the service as performing a small function with a single input and output without global state dependencies. This can be easier to debug.
