Fail to transfer coin between two valid address

[raghavdhingra]

I have set up a full local node using kava start command.
I am using Javascript SDK from transferring coins between two valid kava addresses (obtained using Keplr and trust wallet).

When I am initiating the transaction using the following function:

const txHash = await client.transfer(recipient, coins);
const txRes = await client.checkTxHash(txHash, 15000);

It throws an error:

Status: 400
Status text: Bad Request
Error: rpc error: code = NotFound desc = rpc error: code = NotFound desc = account kava1yr79e73njkrjc0qg3sl444l0mq4gk78p0kngsv not found: key not found

And the value of transaction Hash txHash is undefined

I am following the current documentation to set up the node as well as creating the transaction using the Kava official Javascript SDK.
