Indexes in Error state when following migrate procedure

[stephenp]

I've made a copy of my java app and I'm trying to deploy the HRD version. I get the "new version is ready to start serving", but then under "Uploading index definitions." I get the following:

java.io.IOException: Error posting to URL: https://appengine.google.com/api/datastore/index/add?app_id=carglyplatform&version=2-0&

400 Bad Request

Cannot build indexes that are in state ERROR.

And then some instructions on how to vacuum my indexes. Which seems odd because there's no data yet. The admin console shows all the indexes in "error".

I found at least one other person whose run into this: http://code.google.com/p/googleappengine/issues/detail?id=6275

Any help would be greatly appreciated.

Thanks,

Stephen
