Python Insert All executes with no errors. No data loaded into BigQuery

I am running a big query upload with JSON data using AppEngine.  The code I am 
running looks like this:

#Field Processing and Calls to Client
while CurrentPosition < TotalIssues:
    IssuesList = IssuesPage['issues']
    CurrentPosition += (IssuesPage['maxResults'])
    TransformedIssues = []
    while len(IssuesList) > 0:
        Issue = IssuesList.pop()
        Issue['fields']['key'] = Issue['key']
        TransformedIssues.append(self._TransformIssue(Issue['fields']))
    InsertResponse = self.BQClient.InsertRows(Constants.DATASETNAME, InsertTableName, TransformedIssues)
    IssuesPage = self._GetPagedIssues(Opener, startAt=CurrentPosition)

#BQClient.InsertRows()
def InsertRows(self, dataset, table, rows, insertIDKey=None):
    TableData = self.Service.tabledata()
    RowsData=[]
    for row in rows:
        RowDict = {}
        RowDict['json'] = row
        if insertIDKey in row: RowDict["insertId"] = row[insertIDKey]
        RowsData.append(RowDict)

    Data = {
        "kind": "bigquery#tableDataInsertAllRequest",
        "rows": RowsData
    }

    try:
        Response = TableData.insertAll(
            projectId=self.ProjectID,
            datasetId=dataset,
            tableId=table,
            body=Data
        ).execute()

        sleep(1)
        if Response.get('insertErrors'):
            for error in Response['insertErrors']:
                self.Log.AddLog("ERROR", "BigQueryClient", "FailedToInsertRow. {0}".format(str(error)))
                raise
        return Response
    except HttpError, e:
        self.Log.AddLog("ERROR","BigQueryClient","Unable to insert rows in table: Error:{0}".format(repr(e)))
        return {
            'insertErrors': [{
                    'errors': [{
                    'reason': 'httperror',
                    'message': e
                    }]
                }]
            }

The Response returns with no insertErrors in the dictionary,  however when 
errors are purposefully introduced BigQuery returns the appropriate errors.  
Also the app is able to create a table earlier in the same execution so I am 
sure the connection is good.

However once execution is completed,  when I go to query the table, there are 
no rows.  I am unable to locate any administrative dashboards or logs to debug 
this issue myself.
