Debugging a “cannot read properties of undefined” error [closed]

quire often I find myself coming accross this error:

   main.96977df238dbd452662b.js:1 ERROR TypeError: Cannot read properties of undefined (reading 'label')

what will be the best approach to track who’s the problematic key.
In my expreince this usually happens when I have an object in which i “assume” object has property for example: item.label will cause the error above.

  • just a though: wouldn’t it make lots of sense for javascript to present the name of the key that caused the fail?
