I cant deploy contract on geth

Question

I am trying to deploy my contract using geth on my private network. When i use truffle mirate --reset shows that is has been deployed but the metamask gives me an error( ALERT: Transaction Error. Exception thrown in contract code metamask). So i am using this command eth.getTransactionReceipt with the transaction hash to see if it's ok but the transactionIndex = 0. I read that if transactionIndex = 0 the contract is not deployed. Right? Can you help? I tried to deployed in remix with the provider of my netowrk and it gives me this error (gas required exceeds allowance (8000000) or always failing transaction)

Below i have the contract code.

    pragma solidity ^0.5.8;

        string name;

Maybe you need to convert code to bytecode.
