I was following the Getting Started guide for Google App Engine and got to the step "Uploading your application". When I uploaded my application the Data Store Index never made it to status Serving, instead it went to Error.
I removed the datastore-indexes-auto.xml and created my own datastore-indexes.xml in the WEB-INF directory to see if that helps. When I tried uploading I get the "Cannot build indexes in ERROR" message as per this link
I follow the instructions and comment out my <datastore-index> element and run appcfg vacuum_indexes Guestbook\war. This moves the index into Deleting state but then it eventually goes to ERROR again instead of being removed. I tried creating a new index and the same behavior happens for both. I can't get rid of them!
Can anyone shed some light?
