Thank you for reaching out to us. This error looks to be an issue with the 
client library. Could you go to the github page for the client library you've 
chosen and post this concern under the "Issues" tab, and our client library 
support team will be more than happy to assist you with your concern. Let me

What possibly could be the reason for this?
Thank you.
