Hi @danielbate I am currently trying to read metadata From NFT contract , But its returning something else.
Typescript code :
const { Provider, Wallet, Contract, getRandomB256 } = require('fuels');
const { abi } = require('./abi');
async function main() {
let contractId = '0xdd723a38d1fe832f231fc6ffc69b5dc51850b5fc7f4b5b03f9fa11821877c5ca';
// Create a provider, with the Latest Testnet URL.
const provider = await Provider.create('https://testnet.fuel.network/v1/graphql');
// Initialize wallet with a private key
const privateKey = ''; // Replace with your private key
const wallet = Wallet.fromPrivateKey(privateKey, provider);
const contract = new Contract(contractId, abi, wallet);
// Fetch total assets
const { value } = await contract.functions.total_assets().get();
console.log("Value of Total Assets:", Number(value));
// // Define assetId and metadataKey
const assetId = { bits: '0x2f18e07d3177f6fa66b9999c2174d5d027e659f3f44bd5b9d449c43df12d7559' }; // Replace with actual asset ID
const metadataKey = 'https://arweave.net/LxILnA3lG-oRW5eZR4XAB-RnzpcFRjhSwh_PfQmw1Jw';
// Create the Metadata::String variant
const metadataEnum = { String: metadataKey };
const metadata = await contract.functions.metadata(assetId, metadataKey).get();
let metaKey = metadata.callResult
console.log("Metadata:",(metaKey.receipts[1]));
}
main().catch(console.error);
Response I am getting :
Fuelup show versions

Contract code for getting metadata
impl SRC7 for Contract {
/// Returns metadata for the corresponding `asset` and `key`.
///
/// # Arguments
///
/// * `asset`: [AssetId] - The asset of which to query the metadata.
/// * `key`: [String] - The key to the specific metadata.
///
/// # Returns
///
/// * [Option<Metadata>] - `Some` metadata that corresponds to the `key` or `None`.
///
/// # Number of Storage Accesses
///
/// * Reads: `1`
///
/// # Examples
///
/// ```sway
/// use src_7::{SRC7, Metadata};
/// use std::string::String;
///
/// fn foo(contract_id: ContractId, asset: AssetId) {
/// let contract_abi = abi(SRC7, contract_id);
/// let key = String::from_ascii_str("image");
/// let data = contract_abi.metadata(asset, key);
/// assert(data.is_some());
/// }
/// ```
#[storage(read)]
fn metadata(asset: AssetId, key: String) -> Option<Metadata> {
storage.metadata.get(asset, key)
}
}
set Metadata code :
const { Provider, Wallet, Contract, getRandomB256 } = require('fuels');
const { abi } = require('./abi');
async function main() {
let contractId = '0xdd723a38d1fe832f231fc6ffc69b5dc51850b5fc7f4b5b03f9fa11821877c5ca';
// Create a provider, with the Latest Testnet URL.
const provider = await Provider.create('https://testnet.fuel.network/v1/graphql');
// Initialize wallet with a private key
const privateKey = ''; // Replace with your private key
const wallet = Wallet.fromPrivateKey(privateKey, provider);
const contract = new Contract(contractId, abi, wallet);
// Fetch total assets
const { value } = await contract.functions.total_assets().get();
console.log("Value of Total Assets:", Number(value));
// // Define assetId and metadataKey
const assetId = { bits: '0x2f18e07d3177f6fa66b9999c2174d5d027e659f3f44bd5b9d449c43df12d7559' }; // Replace with actual asset ID
const metadataKey = 'https://arweave.net/LxILnA3lG-oRW5eZR4XAB-RnzpcFRjhSwh_PfQmw1Jw';
// Create the Metadata::String variant
const metadataEnum = { String: metadataKey };
// Call set_metadata function with the correct parameters
const metadata = await contract.functions.set_metadata(assetId, "This is NO NFT", metadataEnum).txParams({ gasPrice: 1 }).call();
let txn = await metadata.waitForResult()
console.log("Metadata:",txn.transactionResponse);
}
main().catch(console.error);
Do we need anyother details to Provide over here.
