技術メモ: datastore_errors.BadArgumentError:

2008年11月5日水曜日

以前 SDK で動作していた script が動かなくなった。

以下の一行の追加が必要

When I upgraded to 1.1.3 from 1.1.2, my App Engine unit tests (built
using the scheme described in another post [1]) started failing with
the following stack trace:

google.appengine.api.datastore_errors.BadArgumentError: _app must not be empty.

I added the following in my test setup:
os.environ['APPLICATION_ID'] = APP_ID
