Using the dev server, I am trying to display some image files stored
in the blobstore. However, when I call images.get_serving_url(), I get
a python error saying that the BlobKey passed in to the function has

I presume something else is wrong.
I will paste the traceback below -- can anyone help me figure out what
is wrong?
