新手第一次用阿里云的产品。在函数计算写代码获取表格存储的数据，执行日志一直显示timeout，函数执行状态函数执行失败(UnhandledInvocationError)。

函数计算里的代码：

-- coding: utf-8 --

import datetime
from tablestore import *

INSTANCE_NAME = 'WLQC2019'
REGION = 'cn-shanghai'
ENDPOINT = 'https://%s.%s.ots-internal.aliyuncs.com'%(INSTANCE_NAME, REGION)
TABLENAME = 'T_User'

def get_ots_client(context):
creds = context.credentials
client = OTSClient(ENDPOINT, creds.accessKeyId, creds.accessKeySecret, INSTANCE_NAME, sts_token = creds.securityToken)
return client

def handler(event, context):
CardID = "AB45TG7HT3"
primary_key = [('CardID',CardID)]
columns_to_get = []

client = get_ots_client(context)

now = datetime.datetime.now().strftime('%Y%m%d%H%M%S')
cond = CompositeColumnCondition(LogicalOperator.AND)
cond.add_sub_condition(SingleColumnCondition("StartTime", now, ComparatorType.LESS_EQUAL ))
cond.add_sub_condition(SingleColumnCondition("EndTime", now, ComparatorType.GREATER_EQUAL ))

consumed, return_row, next_token = client.get_row(TABLENAME, primary_key, columns_to_get)
return return_row.primary_key

执行日志
