este es mi codigo

 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')); } });

el error esta en la linea

abiDefinition=JSON.parse(compiledCode.contratos[':Votación'].interfaz)
