Summary field is truncated in thread returned from API

Summary field is truncated in thread returned from API

I am using the API to get all the threads of a ticket.  I retrieve the ticket, then I list the threads and then I get each thread.  The issue that I am having is that the 'summary' field of the retrieved threads is being truncated - 
returns the full thread but the summary is truncated:
           "status": "SUCCESS",
            "summary": "Hello Nick, <text removed> and switch to it to see Salesf...",
            "author": {

Is there a way to retrieve the thread with the full summary text?
