Error while running project

Hi Mohammed, nice to meet you.

I was able to launch your project. You have done an awesome job, thank you so much!
Still I'm finding troubles, cause after launching this error appears:

I'm sorry, but I'm not an experienced python programmer at all, could you please help me to find what I'm doing wrong?
Thank you in advance!

Hi, maybe mistake in config.json. Can you show your config file without api keys
