bitcoin-cli dumpwallet gives the same error.

No transactions have been made to or from this wallet yet. I created it with Bitcoin Core. I'm hoping to use this wallet for mining. I also want a copy on my iPhone in the Bitcoin.com wallet app. I don't know what's broken here. I compiled from GitHub source. No GUI.

Any ideas?
