Question

I can not find what the problem is, someone can help me

Contract

pragma solidity ^0.5.9;

contract certificarProceso {

    address public creador;
    address emisor;
    string informacion;
    string informacionHashArchivo;

    function escribirInformacion(string memory informacion1, string memory informacionHashArchivo1) public {
        informacion = informacion1;
        informacionHashArchivo = informacionHashArchivo1;
    }

    function getInformacion() public view returns (string memory) {
        return informacion;
    }

    function getInformacionArchivoHash() public view returns (string memory) {
        return informacionHashArchivo;
    }
}

Answer 1

the problem is that the contract's address is undefined.

in the console remove the keyword var in the instantiation and keep just :

address ="0x93ba4ede5903c6656060c443255ed4ef569a5144"

same for abi ...

you can check afterwards if the value set by just typing the variable name in the console

exp

> address

0x93ba4ede5903c6656060c443255ed4ef569a5144

Answer 2

I thank you for your answer. I corrected what you indicated to me, but unfortunately it throws the same error. Then I tried another contract to rule out that I see a problem with that contract, but I also throw the same error

I am testing from the console because from my java application with web3j I get the following error when I want to read a variable of my contract

Error org.web3j.tx.exceptions.ContractCallException: Empty value (0x) returned from contract

And when I want to write a variable throws

org.web3j.protocol.exceptions.TransactionException: Transaction has failed with status: 0x0. Gas used: 4300000. (not-enough gas?)

thank you very much for your help

Answer 3

I made a new contract to carry out new tests, and I made the same mistake. I do not know where to look anymore. I would appreciate if someone helps me regards

contract

pragma solidity ^0.5.9;

contract certificarProcesoNuevo {
   struct  Informacion {
        string  informacion;
        string informacionHashArchivo;
    }
    mapping(string => Informacion) public historialInformacion;
    function escribirInformacion(string memory informacion,string memory informacionHashArchivo, string memory txn) public  {
        historialInformacion[txn].informacion = informacion;
        historialInformacion[txn].informacionHashArchivo = informacionHashArchivo;
    }
    function  getInformacion(string memory txn)  public view returns  (string memory) {
        return historialInformacion[txn].informacion;
    }
    function  getInformacionArchivoHash(string memory txn)  public view returns  (string memory) {
        return historialInformacion[txn].informacionHashArchivo;
    }

}

Console

> eth.defaultAccount ="0x2fef34e4d5a83a7bd78b2b09eb3619046eb1eaa1"
