Hi Rakesh,

This kind of error usually occurs when the access token or refresh token is invalid or incorrect. Could you confirm if you followed this guide (or similar guide) to generate a refresh token? If no, could you try to generate a new refresh token by following the guide and retry your request?

Please let me know if the issue persists after trying the suggestion.
