如何追踪TypeScript中signMessage的调用方并获取stake的txId？

• 我有一个名为signMessage的TypeScript函数，在发送交易（智能合约调用）时会被触发，它位于项目的src/NEAR/NEARFireblocksSigner.ts文件第44行。
• 调用stake函数时，日志明确显示signMessage已被调用，但我在stake函数内部以及它调用的所有函数中，都找不到调用signMessage的代码。
• 我需要让stake函数返回交易的txId值，但不知道该从何处获取这个值。

stake函数代码 #

async stake(amount: number): Promise<void> {
    await this.runSetupIfNeeded();
    typecheck(amount, typeof 1);
    this.log('Validating stake request.');
    let nearWallet = await this.fbks.getVaultAccountAsset("" + this.vaultAccountId, this.assetId);
    let nearInWallet = nearWallet.available;
    if (Number.parseFloat(nearInWallet) < amount) {
        throw new Error(`Vault account ${this.vaultAccountId} has ${nearInWallet} NEAR, but requested to stake ${amount}.`);
    }

    this.log('Validated.');
    this.log('Note - stake,unstake and withdraw will print data including reciepts for transaction, make sure to save it for future reference.', 'WRN');

    (this.config.signer as NEARFireblocksSigner).setNote(`NEAR Staking - Staking ${amount} NEAR`);

    // @ts-ignore - required because deposit_and_stake is generated at runtime.
    let response = await this.contract.deposit_and_stake({
        args: {},
        amount: parseNearAmount("" + amount)
    });

    this.log(`Staked ${amount} NEAR to ${this.contractName}.`);
}

我尝试过调试函数调用，但没有效果。虽然编译后的JavaScript代码显示signMessage被多次调用，但始终找不到它的调用位置。
