如何获得沃森助理日语日志

Question

为了获取Watson助手的日志，我执行了以下代码。在获得的日志中，日本日志被篡改了。 我有一本英语会话日志。你能告诉我对策吗

 #set assistant info
 import json
 from watson_developer_cloud import AssistantV1

 assistant = AssistantV1(
     version='2018-09-20',
     iam_apikey='XXXXXXX',
     url='https://gateway.watsonplatform.net/assistant/api'
 )

 # set workspace id
 workspace_id='XXXXXXXX'

 # get logs
 response = assistant.list_logs(workspace_id).get_result()
 print(json.dumps(response, indent=2))
