Identify the root cause, and describe in simple terms why the code broke. Use examples if necessary. Audit other code that consumes the same/similar data or components. At this point, if the fix is straightforward and has no potential side-effects, implement. If the fix impacts other pages/components, make sure to find all the places they are used, and check/test that nothing broke. In order to merge a PR, there must be a video for every downstream component that is modified upstream. If, as the result of your investigation, there is ambiguity in these instructions, don't write code and instead explain the problem and ask concise questions to identify the correct course before proceeding.
