Of course, often the honest answer is "I don't know the solution to your issue, and finding it would take me X hours of debugging (assuming StackOverflow doesn't know the answer)." So you should probably say that instead, perhaps with some pointers on how you'd go about said debugging. Worse, depending on the size of the project, switching to a different tool just to fix one hard-to-debug issue might genuinely be the easiest option. Of course, doing so without at least trying to debug the issue at hand is slightly insane.
