Datastore admin is unable to delete entities

[A. Kong]

Hi,

I wonder if datastore admin is broken recently.

I went into a datastore admin to select some entities to be deleted permanently.

The entities could not be removed. 

Here is one of the error messages in the log

HTTPNotFound: The resource could not be found. 

I have done it before a couple of month I did not have this problem

How can I fix it?

We've seen this happen when the 'default' task queue has the 'target' overridden in queue.yaml / queue.xml, so that the push tasks needed for the mapreduce jobs are not executing on the default module for 'ah-builtin-python-bundle' but on some other, possibly invalid module / version. I'd recommend checking your queue configuration and ensure that you are not overriding the target for the default queue.
