In some placed Where it is used, it receives, besides other props, the onFocus and onBlur props, but inside it these 2 props are null (the default value set with PropTypes). I put a breakpoint inside its render method and there it seems to receive them as null. So I try to find where that component is used. The Chrome DevTools display just a partial async call stack so I think I will use a component that has a constructor instead of a functional component and put a breakpoint inside the c-tor. I will post here updates if I solve this issue. If you have any ideas on how to solve the issue please let me know here.</p> <p>Thanks.</p> react
