Use Magic to fix the errors in your code
Use Magic fix to detect and fix errors in your code. Whenever a cell returns an error, it will display the "Magic fix" button in the error output, which you can click to quickly launch Magic fix.
If you suspect your code has an issue but there is no visible error, Magic fixes can also be triggered manually with
Cmd/ctl+shift+, or from the Magic menu. In this case, it is often better to use a Magic edit and specifically describe what you think the issue may be.
