addWithDupCheck function does not return any response or exception

We have a cron to add tags to attendees and we check for attendee with addWithDupCheck in case contact is not found for the attendee. In most of the cases, addWithDupCheck is returning no value or throwing no exception. Please suggest how should we tackle this problem?

Hi Arvinder,
When you make the call with the dup check option what is actually being returned? What is the HTTP code being returned, what is an example response you are seeing? Is the contact not being created? Is it not properly dup checking/updating? Please provide me with a little more detail on exactly the problem you encountering and the response you are seeing and I’ll be better apt to help.

It was some mistake at our end as we were using an incomplete infusionsoft object to call the addWithDupCheck
