TypeError: Cannot read property 'decimal' of undefined when signing contract

[Wabinab]

Hi.

I tried to make a transaction using here wallet, but this problem in the title keeps popping up.

I wonder if it has anything to do with the sdk. I don't directly use this sdk, but via near-wallet-selector. After logging in, I perform the call as below:

import { providers } from 'near-api-js';

async call(method: string, args = {}, deposit = "0") {
    if (this.get_account_id() == null) {
      console.error("please sign in.");
      return;
    }
    const gas = '30000000000000';
    const outcome = await this.wallet.signAndSendTransaction({
      signerId: this.account_id,
      receiverId: this.contract_id,
      actions: [{
        type: 'FunctionCall',
        params: {
          methodName: method,
          args,
          gas,
          deposit
        },
      }]
    });

    return providers.getTransactionLastResult(outcome);
  }

and an example function that cause the error looks like this (it's located in a service file in Angular):

this.walletService.call('activate_receipt', {}, utils.format.parseNearAmount("0.1") ?? "0")

(Note: the above function isn't the only one causing the error. Calling other functions also cause the decimal error).

I wonder what was causing the error. In essence, running the same code in MyNearWallet is successful; yet, it doesn't pass with Here Wallet.

The code is run on testnet. Wallet is connected to testnet as well.

Though one notice one thing: despite wallerhere.testnet (the connected account) having positive non-zero balance, it displays the account balance as $0. Does that affect it?
