Ropsten Testnet get NFTs

Moralis General
#1

Hello, I want to get all of the NFTs for a wallet on the ropsten testnet, however the code is giving me this error

Uncaught (in promise) Error: Invalid or unsupported chain “ropsten” at handleError

This is my code:

const options = {chain: “ropsten”, address: ‘0x94Fb04A09022D48007e55Bbab7f2e5fabce08ffb’}
const nfts = await Moralis.Web3.getNFTs(options)

#2

Is that really how you are calling it?
Shouldn’t it be await Moralis.Web3API.account.getNFTs()?

Also just try “0x3” instead of ropsten might work

#3

Yes it works for the eth and matic main nets it doesnt work for the ropsten testnet

Error: Invalid or unsupported chain “0x3”
at handleError

#4

How about “testnet”? Also do you have ropsten selected on the server you are using?

#5

As @kone mentioned, it should be Moralis.Web3API.account.getNFTs() which works fine.

const options = {
    chain: "ropsten",
    address: "0x94Fb04A09022D48007e55Bbab7f2e5fabce08ffb",
};
const nfts = await Moralis.Web3API.account.getNFTs(options);
console.log(nfts);
#6

I dont want to use moralis for the authentication part. I just want to use it to get all the NFTs

#7

You don’t have to? Pretty sure it should work even if you authenticate with something else or not authenticate at all

#8

Whats the entire code snippet, because this is the error:

Uncaught (in promise) Error: Web3Api not initialized, run Moralis.start() first

#9

You haven’t run Moralis.start()?

#10

I have but now the entire page is just white and wont load

#11

Moralis.start({ serverUrl: “SERVER_URL”, appId: “APP_ID” })

#12

What are the errors you are getting?

#13

oh I didn’t know you were using react (sorry for the late reply btw).
Check this (click on the react tab if something else is selected for the code example)
https://docs.moralis.io/moralis-dapp/web3-sdk/account#getnfts

if you are using it in react, check the doc https://docs.moralis.io/moralis-dapp/connect-the-sdk/connect-with-react. You have to wrap the App component with MoralisProvider.
