While using the Salesforce Source, the following error message was returned.
'MALFORMED_QUERY: unexpected token: True'
MALFORMED_QUERY is a dead giveaway that the query sent to Salesforce was not in proper syntax. This is not a COZYROC error message. You will need to use Fiddler Tracing app to do trace of what is sent to Salesforce to cause the error being returned or contact Salesforce to do server side tracing. Search the web for MALFORMED_QUERY and you will see the message is Salesforce specific.
