Since I switched my App Engine app to a flexible environment, it seems that all tasks failed to run. I was surprised that all tasks failed. But when I open the logs, I got only this:
01:33:56.026POST500167 B4 msAppEngine-Google; (+http://code.google.com/appengine)/_ah/queue/deferred The status code is 500, but when I expand it, there is only this information inside: 0.1.0.2 - - [29/Sep/2016:01:33:56 +0800] "POST /_ah/queue/deferred HTTP/1.1" 500 167 http://0.xxxxxxx.module-sync.xxxxxxxxx.appspot.com/_ah/background "AppEngine-Google; (+http://code.google.com/appengine)" "module-sync.xxxxxxxxxx.appspot.com" ms=4 cpu_ms=0 cpm_usd=1.8663e-8 loading_request=0 instance=- app_engine_release=1.9.45 trace_id=- { metadata: {…} protoPayload: {…} insertId: "2016-09-28|10:34:00.180396-07|10.106.31.139|1292268011" log: "appengine.googleapis.com/request_log" httpRequest: {…} operation: {…} } There is no exception or stack trace or anything else that I usually see when I was using the standard environment. How can I troubleshoot this? Why are my deferred tasks not run? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
