[Error] Cannot deploy contract onto Testnet

What I am doing

I am trying to deploy smart contract onto testnet shasta. But whenever I try to deploy a contract it always shows OUT_OF_ENERGY error.

Expected Behaviour

Contact should be deployed successfully onto Testnet.

Actual Behaviour

When I try to migrate a smart contract using tronbox it shows below error.

ERROR: Contract Election has not been deployed on the network.
For more details, check the transaction at:
https://api.shasta.trongrid.io/wallet/gettransactionbyid?value=1deabb8330f39f6a153781fb7e3ce83c2ba2c31914e14d5d99fc37db95e20038
If the transaction above is empty, most likely, your address had no bandwidth/energy to deploy the contract.

Even if I have enough energy for deploying the smart contracts.

This is the configuration that I had added in the tronbox.js file.

shasta: {
      privateKey: 'edec2a9abe800b8f71288cb0315b682e8257f2c7553a3503cae7b4a362cd787f',
      consume_user_resource_percent: 100,
      fullNode: "https://api.shasta.trongrid.io",
      solidityNode: "https://api.shasta.trongrid.io",
      eventServer: "https://api.shasta.trongrid.io",
      network_id: "*"
    }

And this solidity contract code that i want to deploy in the test network.

pragma solidity ^0.4.25;

contract Election{

    struct Candidate{
        uint id;
        string name;
        uint voteCount;
    }
    mapping (uint => Candidate) public candidates;
    uint public candidatecount;
    mapping (address => bool) public voter;

    event eventVote(
        uint indexed _candidateid
    );

    function addCandidate(string _name) public {
        candidatecount++;
        candidates[candidatecount] = Candidate(candidatecount,_name,0);
    }

    function vote(uint _candidateid) public {
        require(!voter[msg.sender]);
        require(_candidateid > 0 && _candidateid <= candidatecount);
        voter[msg.sender] = true;
        candidates[_candidateid].voteCount ++;
        emit eventVote(_candidateid);
    }

}

Any help would be highly appreciated.

The same issue here, do not matter the size or complexity of the code, event the startup codes, I'm not able to deploy them due to OUT_OF_ENERGY error.

I'm thinking that maybe there is too much TRX freeze on test network, idk.

@mrsirja @fakel The energy limit proposal on main-net doesn't take effect on shasta, because the block height of shasta doesn't reach.

Since this is shasta related issue, please ask solution from them.

@jiangyy0824 Where can I ask them?

[fakel]

@mrsirja probably as @jiangyy0824 state, the main-net doesn't take effect on shasta, however, after some debugging I found some messages that seem to state a limit on energy to around ~19k and a single store operator consuming around ~20k and dropping the transaction there.

Trying the same transaction on main net went well, without problems so, yes, probably a Shasta problem.

Hello @fakel and @jiangyy0824, Thank you for your kind response. You both are right. There is a problem with Shasta energy limit. I tried to deploy a contract using a newly created account without any energy. So deployment of a contract will burn some TRX and it is working successfully.

Because I found a solution, I'm closing this issue now.

Uhm, @ghost can you paste your solution here? Thanks.

Did you or anyone find out? I am looking for answers now as well :)
