Dear all,
I believe I have found the problem. The problem was related to the urlfetch
call (I don't know if dd has also a urlfetch call, could you please tell
me???). I did many tests until I isolate the problem. When i did calls only
to datastore everything worked as expected. However when I added the
urlfetch call it produced the 204 errors. It happened always so I believe
that could be a bug.
What I did to get rid of the error was to remove the cloud end point from
Google and use a basic servlet. I found that mixing the servlet with the
urlfetch call we don't get the error, therefore the problem might not be
only related to urlfetch but a combination of urlfetch and Google cloud end
point.
We also talked with Google support, they said that the urlfetch problem
could be related to our location. I'm in Madrid and our users are in
Europe. They said that most of GAE's API are in the states, so that might
be a problem.
