python - Google スプレッドシートに行を追加するときの TypeError (Python を使用)

Question

これを使用してスプレッドシートに行を単純に挿入しようとしています:

# this is how I create the spreadsheet document
doc_client = getDocAPIService(user_id) # a separate function handles oauth and returns the doc client
doc = gdata.docs.data.Resource(type='spreadsheet', title='test')
doc = doc_client.CreateResource(doc)
spreadsheet_key = doc.GetId().split("%3A")[1]

# I then try to manipulate the spreadsheet
fields = {'test': 'test'}
sheet_client = getSpreadhseetAPIService() # again, a separate function handles oauth
entry = sheet_client.InsertRow(fields, spreadsheet_key, wksht_id='od6')

ワークシートを追加してフィードなどを取得することはできますが、行を追加すると次のエラーが発生します。

TypeError: unbound method _AddMembersToElementTree() must be called with ExtensionContainer instance as first argument (got SpreadsheetsList instance instead)

これらは、重要な場合に備えて、クライアントを取得して oauth を処理するためのヘルパー関数です。

def getDocAPIService(username):
    two_legged_oauth_token = gdata.gauth.TwoLeggedOAuthHmacToken(
        config.OAUTH_CONSUMER_KEY, config.OAUTH_CONSUMER_SECRET, username)
    client_docs = MyDocsClient(source="myapp")
    client_docs.auth_token = two_legged_oauth_token
    client_docs.ssl = True
    client_docs.http_client.debug = True
    client_docs.http_client.deadline = 30
    return client_docs

def getSpreadhseetAPIService():
    gdocs = gdata.spreadsheet.service.SpreadsheetsService(source="myapp")
    gdocs.SetOAuthInputParameters(gdata.auth.OAuthSignatureMethod.HMAC_SHA1, config.OAUTH_CONSUMER_KEY,
                                  consumer_secret=config.OAUTH_CONSUMER_SECRET)
    gdata.alt.appengine.run_on_appengine(gdocs)
    return gdocs

これは完全なトレースバックです:

    atom.ExtensionContainer._AddMembersToElementTree(self, tree)
TypeError: unbound method _AddMembersToElementTree() must be called with ExtensionContainer instance as first argument (got SpreadsheetsList instance instead)

これはなぜですか？

ありがとう、
