Unable to grade an assignment 0 with a vague error message

[Jayne1010]

When I attempted to grade an assignment 0, it does not allow me to even though in real life students are allowed to be graded 0. Additionally, the error message is not helping as it say invalid arguments but I am also not sure which arguments are invalid.

Team's Response

The Planned Enhancements section the DG has mentioned of our future plans to allow grading with a score of 0.

• [x] I disagree

Reason for disagreement: As much as it has been mentioned in the UG, the error message could be clearer for each parameter, and in this case if I input a invalid score, it could have said something like Invalid score inputted rather then just saying it is invalid argument.
