What is the best approach to solve a bug or implement features that involve external codebases?

Already found what I was looking for. Thanks so much for creating this community: https://www.jointaro.com/question/ZRneLgwmrM2JLCrGn5Rz/im-trying-to-fix-a-p1-bug-but-some-relevant-code-is-owned-by-another-team-unsure-about-ownership-and-how-to-proceed/

I hope these other resources are helpful as well!

• "How can I root cause bugs faster?"
• "How can I become more independent and better at unblocking myself with tricky technical issues?"
• "What is the effective way to understand new repository in order to make the required changes in that repo?"

Summarizing all the wisdom from these threads:

• Be excited about these opportunities and treat them as an opportunity to collaborate with others and expand your learning.
• Bias towards action. Try changing the code and seeing what happens. Add all the log statements ever and see what surfaces. Don't get stuck reading.
• Understand the overall flow end to end. Everything in tech is a series of steps.
