Parity-ethereum: web3.personal.unlockAccount call issue

[HatimTim]

I'm running:

• Which Parity version?: 1.10.4
• Which operating system?: Ubuntu 16.04
• How installed?: via deb binaries
• Are you fully synchronized?: yes
• Which network are you connected to?: ropsten
• Did you try to restart the node?: yes

I'm using web3 1.0.0-beta.34 to connect to parity node.
The parity node is started with:

parity --chain=ropsten --jsonrpc-apis "web3,eth,personal,parity_accounts"

and also using

parity --chain=ropsten

The account unlock using the below command is not successful

web3.personal.unlockAccount("0x00C...", "password", 1000);

The error below is generated:
TypeError: Cannot read property 'unlockAccount' of undefined

Please help to solve this issue . Thanks

As of web3.js v1.0, you have to go through eth in order to reach personal from nodejs:

web3.eth.personal.unlockAccount("0x..", "<passs>", 1000);
