Please help me Thank you

The previous release Kronos (v1.12.10) is working fine on my AWS machine But this new one got an error mentioned above

The "etherbase" is the account that should be credited with block rewards and gas fees when you win a block.
Geth's behavior has indeed changed in the last release; you now need to use the CLI option to configure it (whereas in earlier versions, the first account in the keystore was selected by default).

./build/bin/geth --help|grep -A5 -B5 etherbase
   MINER
   
    --mine                         (default: false)
          Enable mining
   
    --miner.etherbase value       
          0x prefixed public address for block mining rewards
   
    --miner.extradata value       
          Block extra data set by the miner (default = client version)

PS. ⚠️ The command you're using there seems to be high risk.

Yes, that should work for you. But again, please be aware that using --unlock --http --http.api "...personal" --mine will allow anyone with access to those HTTP ports to withdraw the funds you may earn by mining.
