GAE : 채널 API : ApplicationError : 1

Question

GAE는 이전에 작동했던 일부 코드에서 ApplicationError : 1을 던집니다. 코드가 오래전에 사용 되었기 때문에 일반적인 GEA 문제이거나 일부 버전 업그레이드 문제 일 수 있습니다. 그 오류를 어떻게 디버깅하겠습니까?

ApplicationError: 1 (/base/data/home/runtimes/python27/python27_lib/versions/third_party/webapp2-2.5.2/webapp2.py:1552)

채널 API가 종료되었습니다. 사용 중지 페이지는 here입니다.

그것은 상태 :

The Channel API did not scale well enough for the workloads it was intended for and so did not find wide adoption. Accordingly, support for the Channel API will be shut down for brief periods of time for maintenance beginning on July 13, 2017, as described in the shutdown timetable. The service will be turned off permanently on October 31, 2017.
