Hi @hudhaifagburi

Here is a post written by one of our mentors on debugging. It is very comprehensive list with various problems that you might be encountered. I hope you might find it helpful.

The compute cost function is not correct. In the error message said that you got a value that doesn’t correspond with what was expected.
