error: relation "heads" does not exist

[eduardg7]

I installed the postgreSql database, I did run npm install inside every subfolder and I wanted to run the index.js from the flashscore folder.

Here is the console. I have to say it's my first time working with postgreSql so I am not sure if it's an error caused by my configuration.
