When you can’t reproduce a bug locally, it’s tempting to just try random fixes and pray. Resist the temptation!
Some ways to get information:
- try to reproduce the environment where it happened
- ask for screenshots / screen recordings
- add more logging, deploy your code, and repeat until you understand what caused the bug
- read the code VERY VERY carefully (incredibly boring but it actually does work sometimes)
- do your experimentation somewhere where you can reproduce the bug (on a staging server? on someone else’s computer?)
