Submitting code Challenges not working (SQL)

Question

Whenever trying to submit a code challenge in SQL the error is always "that there is nothing that my code ouputs" - even that I am 100% sure the code works. Even a basic query "Select X from table Y" gets me to the same error! Frustrating UX.. Any others out there? Doing the challenges with oneplus 8 pro
