Hello, I am also facing this issue, where for the assignment of modules 1 there are lots of grader errors. the first issue is with excercise 4 , where I am getting error
“There was an error grading your submission. Details: ‘test_case’ object has no attribute 'fail”
the second issue I faced is with the excercise 7 and 8 , where I am getting error
“Object required for grading not found. If you haven’t completed the exercise this is expected. Otherwise, check your solution as grader omits cells that throw errors.”
could you please help me to solve these issues, because of this I could not be able to complete the course.
Please find screenshot below
Thanks in advance
