[SOLVED] Await web3.eth.getAccounts(); undefined

[radityaidabagus]

web3 = await Moralis.enableWeb3();
accounts = await web3.eth.getAccounts();
console.log(accounts)

the result came out like this
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘getAccounts’)

can you help me fix this?

[cryptokid]

if you are using latest version of Moralis SDK then you may get an ethers instance instead of an web3 instance by default

[radityaidabagus]

Sorry, I’m kind of new to this scene. I don’t think I understand what you mean. Can you provide an alternative for me to look at the signed-in accounts in my inspect element console with the “ether instance” you said?

Ultimate NFT Programming Tutorial - FULL COURSE

currently following this tutorial and I’m stuck with the getaccounts part I didn’t change or modify the code from the video, so I assume that the problem is just an updated code for —>

accounts = await web3.eth.getAccounts();

[cryptokid]

you could try to read here: Moralis JS SDK v1.0 (migration to Ethers.js)

or try to use a version of the SDK that is not greater than 1.0.0

[radityaidabagus]

updated and It’s still not working the web3.eth.getAccounts function is still not defined.

[cryptokid]

you could try to do some debugging, to see what you have on web3, there are also alternative syntaxes to get that eth address, you can also search on this forum for what solutions were found in other threads for the same problem

[cryptokid]

you can also try: web3.currentProvider.accounts[0]

[radityaidabagus]

web3.currentProvider.accounts[0] didn’t work

[cryptokid]

can you check what you have in web3? if is an web3 instance or an ethers instance

[radityaidabagus]

Moralis.start({ serverUrl, appId });
let web3;

async function init(){
let currentUser = Moralis.User.current();
if(!currentUser){
window.location.pathname = “/index.html”;
}

web3 = await Moralis.enableWeb3();
let accounts = web3.currentProvider.accounts[0];
console.log(accounts)

const urlParams = new URLSearchParams(window.location.search);
const nftId = urlParams.get("nftId");
document.getElementById("token_id_input").value = nftId;
//document.getElementById("token_id_input").value = accounts[0];

}

async function mint(){
let tokenId = parseInt(document.getElementById(“token_id_input”));
let address = document.getElementById(“address_input”)
let amount = parseInt(document.getElementById(“amount_input”))
}

init();

[cryptokid]

this code doesn’t say too much, it may be more important what you have in html file when importing Moralis SDK

[radityaidabagus]

Sure here it is.

@radityaidabagus

<script src="https://unpkg.com/moralis@latest/dist/moralis.js"></script>

from this line it seems that it will be an ethers instance

[radityaidabagus]

Ok so if it’s in ether’s instance what would be the sytax to retrieve the eth address because it seems like some of from the web3js are not working for me.

[radityaidabagus]

I’ve been looking for it in their library but I cant seem to find it. It would be really helpful for you to help me figure it out. Thanks.

Moralis JS SDK v1.0 (migration to Ethers.js)

Migration Guide JS SDK v0.0.x > v1 Removed dependency of web3.js in favour of ethers.js Introducing custom connectors Update To update, you need to update your dependency For CDN:: <script src="https://unpkg.com/moralis@latest/dist/moralis.js"></script> Please update latest to the release version you want to use. For all releases, see: https://github.com/MoralisWeb3/Moralis-JS-SDK/releases Via npm: npm install moralis@latest If you do NOT want to update yet Then you you specify…

you can read there how to use web3 instead of ethers

[radityaidabagus]

Ok thank you cryptokid

[radityaidabagus]

It worked perfectly, I chose the v0.0.184 for the Moralis SDK. Seems like after the Moralis upgrade there’s a problem specifically with the web3.eth.getAccounts(); function. Again, thank you so much for helping me fix my code.

[YosephKS]

Hey @radityaidabagus, great to have you resolved the problem

it is nevertheless highly recommended that you upgrade to the latest version ASAP as new features will only be shipped in the latest ones.

the reason why web3.eth.getAccounts might not work similarly as in v0.0.184 is because there is breaking change where we move from web3js to etherjs as the default.

You still can use web3js with v>1.0.0, just need to follow the migration steps laid out up there by @cryptokid.

Cheers~
