Bug on Learn Git by Building an SQL Reference Object Course

Since 26.06.2022 morning I am trying to continue my progress in Relational Database (Beta) Course => Learn Git by Building an SQL Reference Object => Build an SQL Reference Object course. It says " The first thing you need to do is start the terminal. Open a new one by clicking the “hamburger” menu at the top left of the window, going to the “terminal” section, and clicking “new terminal”. Once you open a new one, type echo hello git into the terminal and press enter." I did exactly what it says 50 times, in the ‘Get a Hint’ section it suggests:

  1. Follow the directions closely

  2. If the tests don’t pass, trash all the terminals with the trash can icon at the top right of the terminal. Then, redo those instructions

I tried those hints 50 times as well, tried with a different browser, refreshed the page, restarted my computer but it doesn’t let me pass to the next step.

Is there anything can be done about these courses? Thank you
