I am having this error when I run my MERN application but it only appears in Google Chrome, in Safari I can run it perfectly.
It seems that it's not reading localStorage correctly and it gets some values as undefined.
I really have no clue about the reason of this problem because it had never happened before and I've been working on this same app for months. I did install and uninstall some things because I was having a strange and sudden error, but I don't see how it can be related to this particular error. I'll be entirely grateful if someone could help me. Thank you very much!
