Unable to move forward in Learn Bash Scripting by Building Five Programs

I’ve been trying to finish that module for 1 week, but the problem is in .freecodecamp/.mocharc.json.
Surely when you want to enter the solution you will see “Test Runner Fail”.
Yesterday I made a post where I commented on the problem, I tried all the possible “solutions” but I had no luck. I leave you the link to my post “Learn Bash Scripting by Building Five Programs - Build Five Programs” and see if with the other post where they indicate how to modify .mocharc.json you can solve it maybe, it didn’t work for me, I even did several full resets and nothing… While I continue with other modules.
Luck
