I would log the input the expected output and the actual output first. Once those three are visible, the bug usually stops feeling mysterious. The the kitchen detail changes the whole answer

Start by reducing it to the smallest reproducible piece then change one variable at a time. The trap is trying to optimize before you have feedback.

- Write down the exact error and the input that caused it.
- Make a tiny example, then add pieces back slowly.
- Keep the final fix boring and well-named.

Come back with what happened; the details will make the next answer better

Try making a tiny reproduction with no framework code. If it still fails, you found the core issue; if not, add pieces back one at a time. I learned that one the expensive way

the safe answer is to keep the API boring: clear names explicit errors and one behavior per function. I used to overcomplicate this constantly
