CALCULAS-Week1 submission keeps failing

I have tried resubmitting multiple times but the week 1 submission keeps failing.
Even though I have passed all the test and assignments.

Programming Assignment: Optimizing Functions of One Variable: Cost Minimization

Could you please tell me what is the problem .

Kindly note that all my individual test passes successfully and I have done it like 10 times today but I cannot submit he assignment because of this problem. Today is the last day for submitting this assignment hence requesting if this resolution could be expedited.

I’m not a mentor for that course, but I can make a guess at the issue.

If “L_of_omega” is a global variable in the notebook, then the grader is not going to have access to it. So check if your code is using “L_of_omega” incorrectly, and maybe you should be using some other variable.

Passing the tests in the notebook does not prove your code is perfect.
