Windchill swagger connector service invocation

We are having requirement of using windchill swagger connector (ptc-windchill-integration-connector).But we dont know how to invoke custom service in that connector for REST call,whether we need to write route or js service in that connector.We want output in the form of info-table. We tried as below but getting error :

var params = {
infoTableName : "InfoTable",
dataShapeName : "DataInfo"
};

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(DataInfo)

var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);
// result: INFOTABLE dataShape: "DataInfo"
result = Things["CDConnector"].Objects_Get_FindObjects({
$filter: 'state eq INWORK' /* STRING */,
typeId: 'wt.part.WTPART' /* STRING */,
navigationCriteria: undefined /* STRING */,
$select: 'objNumber,objName,version' /* STRING */
});

But getting error as 

Error executing service GetPobjects. Message :: Your route exchange has failed. HTTP operation failed with status [500 - 500] - See Script Error Log for more details.
