API Not Accepted

[jbp2021]

I stumbled across this while working on a sentiment analysis for a class assignment and thought I'd try it.

I have an active API but unfortunately don't get the green check mark. I get the "error has occurred" message.

Here's a bit of the error details:

Inner Exception:

Exception Message: Value does not fall within the expected range.
Exception Target Site: get_Item
