  • Hi there. Can you include the exact code you're using for this? – Richard Horrocks Apr 16 '18 at 14:15

Your web3 talks to a node over RPC. If it is a geth node, the personal api is not exposed/enabled by default for security reasons.

Exercise caution.

You might enable it with geth --rpcapi eth,web3,personal in addition to your other parameters.

Hope it helps.

  • Hi Rob, still my problem is not solved, I have updated the question with the code, please check if I am going right? – Shubhabrata Mukherjee Apr 17 '18 at 4:25
