java.lang.IllegalArgumentException: INVALID_BLOB_KEY: Could not read blob.
at
com.google.appengine.api.images.ImagesServiceImpl.getServingUrl(ImagesServiceImpl.java:282)
"
As my 3 projects experience, this error occurs on the local dev server
only. It will return a success serving URL on the production server.
Hope this could help.
