Sending string as address to smartcontract

Question

I have trouble sending an address to a deployed contract, my function looks like this:

function addNote(uint _value, address _owner) public { 
... 
}

and when I'm sending the parameters:

contract.deployed().then(function(instance) {
    return instance.addNote(value,"0x092f90acAbb3b23Aded64D59FB6f6Be97615476b");
})
.then(function(result) {
    console.log(result);
})
.catch(function(error) {
    console.log(error);
});

I'm getting this error:

Error: invalid address
at inputAddressFormatter (/Desktop/Server/node_modules/truffle-contract/node_modules/web3/lib/web3/formatters.js:274:11)

Also when I'm adding the last parameter:

{
    from: "0x092f90acAbb3b23Aded64D59FB6f6Be97615476b",
    gas: 1000000
}

then the error is:

TypeError: Cannot read property 'constructor' of undefined
at /Desktop/Server/node_modules/truffle-contract/contract.js:96:1

What's the problem?

Answer 1

An address is a 20-byte hex number, so you shall not send it as a string. Try:

return instance.addNote(value, 0x092f90acAbb3b23Aded64D59FB6f6Be97615476b);

UPDATE: The problem is not related to the address stringification. Please read below.

The confusing part in your specific example is that you're getting an error which misleads you to believe there's something wrong with the function function addNote(uint _value, address _owner). However, the error is about the invalidity of your web3.eth.defaultAccount address, that is, where are your contract calls executed from.

Right after compiling and migrating your contracts, do this:

web3.eth.defaultAccount = web3.eth.accounts[0];
