Pretty sure the task only checks that you entered the correct command, which you did - so that’s why it passed. Not sure why it’s not giving any output there. Even if there isn’t any rows in the table, or if the table doesn’t exist, it should still give an output.
I’m going to suggest to try the reset steps here @wojciechkoniczynski. I’ve got a feeling that won’t work, but just in case - it will rebuild the database to the point it is supposed to be at the start of the step you are on.
What is that other message that is cut off? something about ‘large object operations’. Is there any other messages like that that may help figure out why it’s not giving output?
