在GAE上部署cron作业的内部服务器错误

Question

I recently signed up and started playing with GAE for python. I was able to get their standard/flask/hello_world project. But, when I tried to upload a simple cron job following the instructions at https://cloud.google.com/appengine/docs/standard/python/config/cron , I get an "Internal Server Error".

My cron.yaml

cron:
- description: test cron
  url: /
  schedule: every 24 hours

The error I see

Do you want to continue (Y/n)?  y
Updating config [cron]...failed.                                                                                                                                                                                                         
ERROR: (gcloud.app.deploy) Server responded with code [500]:
  Internal Server Error.

Server Error (500)
A server error has occurred.

Have I done something wrong here or is it possible that I am not eligible to add cron jobs as a free user?

Answer 1

I was just struggling with this same issue. In my case, I am using the PHP standard environment and kept receiving the '500 Internal Server Error' when I tried to publish our cron.yaml file from the Google Cloud SDK with the command:

gcloud app deploy cron.yaml --project {PROJECT_NAME}

To fix it, I did the following:

1. I removed all credentials from my gcloud client

   gcloud auth revoke --all

2. Reauthenticated within the client

   gcloud auth login

3. Published the cron.yaml

   gcloud app deploy cron.yaml --project {PROJECT NAME}

From what I can tell, the permissions in my gcloud client got out of sync which is what caused the internal server error. Hopefully that's the same case for you!

Answer 2

I was having this problem as well, at about the same timeline. Without any changes, the deploy worked this morning, so my guess is that this was a transient server problem on Google's part.
