Cant call mint function for token

[sway]

I have token that has mint functionality, and when I call mint function I keep getting this error

 mint = async (assetId?: string) => {
    if (assetId == null || this.alreadyMintedTokens.includes(assetId)) return;
    this._setLoading(true);
    const { accountStore, notificationStore } = this.rootStore;
    const { address } = accountStore;
    if (address == null || window?.fuel == null) return;

    const wallet = Wallet.fromAddress(address, window.fuel?.getProvider());
    console.log(assetId);
    const tokenContract = TokenAbi__factory.connect(assetId, wallet);

    try {
      const v = await tokenContract.functions
        .mint()
        .txParams({ gasPrice: 1 })
        .call();
      console.log(v);
      this.setAlreadyMintedTokens([...this.alreadyMintedTokens, assetId]);
      await this.rootStore.accountStore.updateAccountBalances();
    } catch (e) {
      console.log(e);
      notificationStore.notify(
        `You have already minted ${TOKENS_BY_ASSET_ID[assetId].symbol}`,
        { type: "error" }
      );
    } finally {
      this._setLoading(false);
    }
  };

this is the error

It used to work fine before, I have updated fuels and fuels-wallet packages to 0.29.1 version and

Can you share the repo and branch to reproduce this?

[sway]

sure,
here is link to func declaration

sway-gang/sway-lend/blob/dashboard/frontend/src/screens/Faucet/FaucetVm.tsx#L111

[sway]

is there any updates?)

[sarah]

Do the other functions work and this is the only one where you get this error?

[sway]

every call or simulate function fails with this error

[sarah]

Can you try deleting node_modules and try re-installing? It seems to be working on our end.

I did this yesterday before crated topic and now also did it now to be sure all is same. It still keeps giving error

I have found another of creating token contract instance and changed it to this one, but error is still same

import token_abi from "./token_abi.json"

mint = async (assetId?: string) => {
    if (assetId == null || this.alreadyMintedTokens.includes(assetId)) return;
    this._setLoading(true);
    const { accountStore, notificationStore } = this.rootStore;
    const { address } = accountStore;
    if (address == null || window?.fuel == null) return;
 

    const wallet = Wallet.fromAddress(address, window.fuel?.getProvider());  
    const tokenContract = new Contract(assetId, token_abi, wallet);

    try {
   //i have changed here !
      const { transactionId, value } = await tokenContract.functions
        .mint()
        .txParams({ gasPrice: 1 })
        .call();
      console.log(value, transactionId);
      this.setAlreadyMintedTokens([...this.alreadyMintedTokens, assetId]);
    } catch (e) {
      console.log(e);
    } finally {
      this._setLoading(false);
    }
  };

Here is list of token addresses that I want to mint

{
    "name": "Bitcoin",
    "symbol": "BTC",
    "decimals": 8,
    "assetId": "0xdd17dda6eeee55f6d327020e6d61b9fa7b3c2ab205c46cdca690a46966f4e1c7"
  },
  {
    "name": "USDC",
    "symbol": "USDC",
    "decimals": 6,
    "assetId": "0xd7d5e5c1220872e6f42b38f85ae80c6072b1b4723e7a7218bbf6717aca962536"
  },
  {
    "name": "Uniswap",
    "symbol": "UNI",
    "decimals": 9,
    "assetId": "0x76c4fda9074c4509eaf2652f82bace86e2c7a21bf9faff7bf6228034ebc0f8a2"
  },
  {
    "name": "Chainlink",
    "symbol": "LINK",
    "decimals": 9,
    "assetId": "0x71be783354a9bccfa9de0e7edf291797775e4a730d0922a9675258dbb47f557b"
  },
  {
    "name": "Sway",
    "symbol": "SWAY",
    "decimals": 9,
    "assetId": "0x99075448d291a8f8f69e5f3d25a309c38ad38def9f709a69ae4a2aeaed1701fe"
  }

rpc link I use this - https://node-beta-2.fuel.network/graphql

[sway]

also funny note!

every time when I mint tokes for just created address my Fuel wallet extension is breaking down and showing only black screen

@stacio please have a look, might be something wrong with token standard
link to token standard - GitHub - sway-gang/fuel-token-standard: Fuel network Fungible token standard

We have updated our API to get the provider, and it now returns a promise. it would require you to change the code;

from;

const wallet = Wallet.fromAddress(address, window.fuel?.getProvider());

to;

const provider = await window.fuel?.getProvider();
const wallet = Wallet.fromAddress(address, provider);
// or better now
const wallet = await window.fuel?.getWallet(address);

thanks fo help! it worked, but I have faced another problem with this error

Error: Window closed by inactivity after 5 minutes!

But my window was opened only for 10 seconds

[stacio]

Do you have an example for testing this? I think the issue is related to the custom token as mint will return a token we don’t have on the assets list.

[sway]

I don’t have deployed version of code that I am trying to create yet, but I have tested with account that doesn’t have any other tokens except testEth, and yes, problem is exactly in this

[sway]

Looking forward for this feature implementation

Create Asset management tool

Is there any estimation when it will be done?)

[stacio]

@sway This is one of our priorities. We should have it in a couple of days.

Hello @stacio
I have noticed that team has updated @fuel-wallet/sdk package to 0.5.1 version and tried to run same code above with changed api way, so it look like this now

const wallet = window.fuel?.getWallet(this.address);
const marketContract = MarketAbi__factory.connect(
          CONTRACT_ADDRESSES.market,
          wallet
        );
const tx = await market.functions
      .supply_base()
      .callParams({
        forward: {
          amount: this.tokenAmount.toString(),
          assetId: this.baseToken.assetId,
        },
      })
      .txParams({ gasPrice: 1 })
      .call();

but it still fails with same “5 minutes not interaction” error
