Stock Price Checker FCC (PLEASE HELP :))

Hi there. I am going bonkers doing this project. It works fine one second, then suddenly, it crashes. It runs with no errors sometime, while other times it throws multiple errors. Is there something wrong with my code? Or is there something wrong with the API that I use to obtain the stock price? Did any of you experience this sort of problem or is it just me? Please, please, help!

The api I used is https://iextrading.com/developer
