[Ethereum] Getting error insufficient funds for gas * price + value


I have almost searched all of duplicate questions but not getting any help.
Can someone please point out what is wrong why I'm getting error insufficient funds for gas * price + value, I double check and I have enough ether in my test account.

Some console output:

    console.log('web3 version:'+ web3.version);
    web3.eth.net.getId(function(err, res){
        console.log("Net: "+res);
    web3.eth.net.getNetworkType(function(err, res){
            console.log("getNetworkType: "+res);
    web3.eth.getBlockNumber(function(error, result){
        console.log("Block Number: "+result);

    web3 version:1.0.0-beta.34
    Block Number: 3085927
    291 Net: 3
    getNetworkType: ropsten

Per the comments on the question, you need to add a 0x to the beginning of your private key. web3.js often requires this prefix so it knows the string you're supplying is a hexadecimal representation of a byte sequence (like a private key).
