GoError: Error: the method personal_newAccount does not exist/is not available at web3.js

Question

I just installed geth and I start an instance of geth with this command: geth --rinkeby --syncmode=light --http then I attach to that instance with this command: geth attach http://127.0.0.1:8545 and it seems to work well...

personal command return me that:

but on command personal.newAccount() I get this error:

From what I found in a old post: https://ethereum.stackexchange.com/questions/51772/account-created-using-web3-is-not-showing-in-geth-console I should allow personal api on starting command, but right now --rpcapi personal option is not available.

Do you have any idea what I did wrong?

Answer 1

--rpc.enabledeprecatedpersonal geth command-line parameter helped me.
