Looks good @DebadityaPal. Could you add a couple of unit tests for the new exceptions as well? Ideally, we want 100% codecov/patch at all times.

Yes, I should have added the unit tests, it escaped my notice. I'll do it right away.

[AbhinavTuli]

@DebadityaPal you might want to check how to properly test exceptions using pytest. Here's an example from our tests

[DebadityaPal]

@AbhinavTuli would it be helpful if I modified all the tests in the file to use the pytest format?

[AbhinavTuli]

Just merged it. Thanks for yet another great PR @DebadityaPal !
