I'm not sure what I am doing wrong here; my code is almost identical to the
documentation example.
My code:
filename = files.blobstore.create(mime_type='application/octet-stream')
with files.open(filename, 'a') as f:
f.write(json.dumps(oldblocks, separators=(',', ':')))
files.finalize(filename)
Stack trace:
