Keep getting TransientError when call lease_tasks() to pull from Cloud Tasks

[limin xiao]

Beginning from sometime slightly before 10:28 Feb 24, 2019(UTC), suddenly my app started to constantly get TransientError when trying to pull tasks from task queue.

Since the same piece of code worked stably for more than 2 years and there was no new deployment over the project around that time, I believe someone screwed up at the back end.

I hoped Google could quickly note the error and fix it as they always did.

However, 10 days passed and the error still exists.

Can someone help to check what happened?

 

My project runs on App Engine Standard Environment, Python 2.7 runtime.

Here is the printed trace for Exception.

#Again, the same code worked for years and we did no change before the error begins to show up.

Hello Limin,

As a first step, even though you mentioned the errors came out of nowhere, I would try increasing the maximum rate of the queue as this may help in reducing these type of errors.
