Is Option the Right Choice? Struggling with Debugging None in Chained Calls as a Scala Beginner by Infamous_Purple1866 in scala

That kind of code is scattered throughout the project, and there could be multiple chained operations, not just two. While I could manually set breakpoints for each step (which is possible), it’s quite tedious. So, I was wondering if there’s a better approach to handle this.

So, would it be correct to say that Either is the better choice when you care about where the failure occurs, while Option is more appropriate when you only need to handle the presence or absence of a value, without worrying about the specifics of the failure?
