Error: Keypool ran out, please call keypoolrefill first After setting the dash-client in regtest mode, I am trying to generate coins.

No matter what I do, I get the above error.

When I run:

dash-cli -regtest getmininginfo 


I get the below output:

{
   "blocks": 0,
   "currentblocksize": 0,
   "currentblocktx": 0,
   "difficulty": 4.656542373906925e-10,
   "errors": "",
   "genproclimit": 1,
   "networkhashps": 0,
   "pooledtx": 0,
   "testnet": false,
   "chain": "regtest",
   "generate": false
}


How do I set the generate to true.

If I run

enter preformatted text heresetgenerate true,

I get the message that setgenerate is deprecated, on this network I need to use generate which doesn't run.
Unlock your wallet (using walletpassphrase) and run keypoolrefill as the error message says. generate and setgenerate requires keys from the wallet, and if the keypool is empty, they won't work.
