Access Token Throttle reached within Postman Cloud

Access Token Throttle reached within Postman Cloud

Hi

I am having all sorts of issues getting Zoho API calls to work within Postman.  One of it being the token generation.  I can manually run the request and generate an access token just fine, however when I schedule the request in a collection run within Postman, I get throttle limit reached even though it is one request.  What am I doing wrong?  Is this possible within Postman Cloud?

Thanks
