Hi Ajeet,
My apologies for missing the error you have shown. I can see that you are encountering the error CUSTOMER_SERVING_TYPE_REPORT_MISMATCH in your logs. This error is encountered when you are trying to download a report using manager accounts. You can only download
reports using client accounts. Kindly change your clientCustomerId to a client account to avoid this error.
Let me know if this does not solve the problem, and provide the clientCustomerId you are using for investigation.
