当我在 GAE 应用程序上查看日志时,我经常会看到这样的警告消息:
com.google.api.control.Client flushAndScheduleReports: direct send of a report request failed because of endpoints.repackaged.com.google.api.client.http.HttpResponseException: 400 (Client.java:354)
{
"error": {
"code": 400,
"message": "Precondition check failed.",
"errors": [
{
"message": "Precondition check failed.",
"domain": "global",
"reason": "failedPrecondition"
}
],
"status": "FAILED_PRECONDITION"
}
}
但是,客户端应用程序似乎按预期工作,我不明白这意味着什么。
