I thought it meant the object was set to null when it shouldn't have been.

Wait, isn't it more about null being unexpected?

It's about expecting an object but getting something else.

I’m a bit confused. I thought "non-null" meant it should never be null, so maybe it’s option B? But I’m not completely sure.

I feel like this is similar to a question I saw where it was about trying to access properties of a null object. Could it be option A?

I remember something about null objects from practice questions, but I'm not entirely sure if it’s about defining them or just checking their existence.

I'm a little unsure about this one. The wording of the options is a bit tricky. I'm going to re-read the question and the options carefully before making a decision.

I'm feeling pretty confident about this one. The error message is clearly indicating that an object was expected, but it wasn't provided. So I'm going to go with option C.

Okay, I think I've got it. The error is saying that an object was expected, but it was either null or undefined. So option C seems like the best answer.

Hmm, I'm a bit confused by this one. I'm not entirely sure what it means for an object to be "non-null". Does that just mean it has to be defined?

This one seems pretty straightforward. I think the key is understanding that the error message is referring to an object that was expected but not provided.

I'm not sure, but I think A) An object was defined as 'non-null' but the code attempted to set it to null makes sense too.

I agree with Leonora, because if the code is looking for an object and it's not there, that would cause the exception.
