It looks like you have a very old block log with only a single block in it. The format of the block log changed several times before the 1.0 release. Add --delete-all-blocks once to your nodeos command line to start with a fresh chain in the release format. If you restart nodeos after that first time, you should omit the --delete-all-blocks flag to retain your new chain.
