Hi! I need help with a step from “Learn Git by Building an SQL Reference Object,” part of the Relational Database roadmap (https://www.freecodecamp.org/learn/relational-database). I got stuck on the part “It looks good. Add the changes to staging,” where I should simply stage the sql_reference.json file… but it’s not working. I got the error message “You should add the correct file to staging.” Does anyone have any idea what might be wrong?
