Hi Ajit,

Thanks for reaching out to the Google Ads API Forum.

Upon checking the log traces, it appears that the error seems to be related to the client libraries and not the API. You might find this post on the Github Issue Tracker useful to mitigate the error faced on your end. If not, I would recommend posting your concern on the Github Issue Tracker as Java client libraries team will be able to assist you better with your concerns. 

Let us know if you have any further questions.
