It looks like you might be trying to store more than 500 bytes into a StringProperty. If you don't need that property indexed, you can change it to a TextProperty instead.
It should be safe to do, according to this thread: http://groups.google.com/group/google-appengine/browse_thread/thread/282dc825f9c46684 See the difference between StringProperty and TextProperty here: http://code.google.com/appengine/docs/python/datastore/typesandpropertyclasses.html#StringProperty Nick On 17 August 2010 10:37, Coding Social <[email protected]> wrote: > suddenly getting loads of these errors. my app takes a url and > unwinds it but seems to have issues with these long ones... > > 190.206.24.222 - - [16/Aug/2010:17:31:42 -0700] "GET / > map.powertwitter/? > action=parseLink&version=1.38&format=json&linkNumber=189&url=http%3A// > tr.oneriotads.com/EJHnoM2dnojTxygevjqUhMUIbJdZD- > kRERvtxziYRu7bNvSpeuc3tIHhKcFcBjxBVxi3mxxb8uc- > YHHAqO6xO54kb5bQWFgRNiW3infATshVJi09MDSZi7wbdReFf8WKMRI- > HrRfZcaNPjxDi5_WJnuGxzJ1mpyu2-w- > bJEFcbNQGtSxXrdfg5Qj9CQH2lx8UH4ww0Y_gR2a4QHRRBbIA6cJo4DOqxD2SQkskUOpZiy- > hUIqGAJ5dRKG6DQCFq5Tz2I2h9mVqL3- > mfNct0LcXofJ5FxPdTGroOSgMfQz4b79DWsVmW3UtKmamiFQOvo- > dq6qxFvXlWYQwZY2pIT3WNueh61Z09p- > > NDQxtdySKA_54S-5c5BoUwo4iVj6BvOlSiQFkbFUVb7WDA4PvpIUNy7_1E1hQOZhJDJ48weKejYpv7XZvyHtFtqocVzL- > W8oDMlVmKvHdhh-uzw0SXRbHD2W0wuLXNB3hc- > MBQITdlDQJNo3n6HcbBsmXpA4zdhK7BVFpd0J3GybC_eSJFWcL- > > HBCpwj1f2Vn6izPFeAVHylrYqa2eE7GK6MM4hw6WAhsze8BqZXY2EqIxMKd5SmXW79Q9xNjqpAVznjy9l_OR4Ir9q_nL- > qu9qVjNCOLtlHL07G7jPPO3alTw2JA HTTP/1.1" 500 799 "http://twitter.com/"; > "Mozilla/5.0 (Windows; U; Windows NT 5.1; es-ES; rv:1.9.2.8) Gecko/ > 20100722 Firefox/3.6.8 FBSMTWB,gzip(gfe),gzip(gfe)" > "linkmapper.codingsocial.com" ms=34 cpu_ms=19 api_cpu_ms=0 > cpm_usd=0.000740 > > # > E 08-16 05:31PM 42.351 > > Property is 682 bytes long; it must be 500 or less.
