Usual suspects for rejected JSON?

JonathansCorner.com

I am trying to create a table with server-side processing. At present it rejected "{'iTotalRecords':128,'sColumns':['id','approved_date','approval_status','approva­l_id','reference_id','shipping_authorization_number','manufacturer_distributor_na­me','original_amount','open_amount','requestor'],'aaData':[/* 10 entries deleted */]]}", saying, "DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error."

I simplified the JSON, eventually reaching "{'aaData':[]}", and am still getting the same error. Are there other mistakes I could have made that would trigger this error?

don't know about other usual suspects, but the single quotes are invalid.

Thank you; that was the problem.
