What has working with multiple languages been like on your projects?

Hey everyone. I’m exploring a programming-language project and want to understand how people currently work across languages. Thinking about your most recent project where code in different languages needed to work together: What were you building, which languages were involved, and how did they communicate? Did anything go wrong at that connection? If so, what happened, how did you investigate it, and roughly how long did it take? What tools or approaches did you use, and how well did they work? If it was straightforward, I’d like to hear what made it work well too. One concrete example is enough.
