    As per your given screenshot, it seems that you are using the V5 version of the API and still using the old key. Please use the V5 version key from the My Licenses section of your account to avoid this error.

    If you do not see the V5 key in your account then please let us know.

    I only see the V4 key in my account.

    Hi, Please contact the sales or your manager if you get the v4 key. Since for v5, you need to get the v5 key.

    Hope it helps!
