This is my code

app.get('/info', function(req, res){
    var cookie_pass = req.cookies['auth'];
    var cookie_otp = req.cookies['show'];
    if (cookie_pass == null || cookie_pass == '' || cookie_otp == null || cookie_otp == '') {
        res.redirect('/app');
    } else {
        web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
         code = fs.readFileSync('Voting.sol').toString()
        
         compiledCode = solc.compile(code)
         abiDefinition = JSON.parse(compiledCode.contracts[':Voting'].interface)
         VotingContract = web3.eth.contract(abiDefinition)
         byteCode = compiledCode.contracts[':Voting'].bytecode
         deployedContract = VotingContract.new(['Sanat','Aniket','Mandar','Akshay'],{data: byteCode, from: web3.eth.accounts[0], gas: 4700000})
contractInstance = VotingContract.at(deployedContract.address)

        res.sendFile(path.join(__dirname, 'ui', 'clist.html'));
    }
    
});

The error is in the line

abiDefinition=JSON.parse(compiledCode.contracts[':Voting'].interface)

I was trying to build an evoting system based on the ethereum network and when i run the code it is showing as type error
