当试图将一个简单的对象传递给运行puppeteer的异步函数时，出现此错误：
(node:4000) UnhandledPromiseRejectionWarning: Error: Evaluation failed: ReferenceError: userInfo is not defined

这是我的代码：
const checkout = async (page, userInfo) => {
await page.click('#checkout-now'); // click checkout now after adding to cart is done
console.log("Added to cart, going to checkout...");
// waits for form to load
let checkoutFormVisible = await isElementVisible(page, '#order_bn');
while (!checkoutFormVisible) {
checkoutFormVisible = await isElementVisible(page, '#order_bn');
}
console.log("Checkout loaded, filling payment...");
// filling in billing
await page.$eval('#order_bn', el => el.value = userInfo.name);
await page.$eval('#order_email', el => el.value = userInfo.email);
await page.$eval('#order_tel', el => el.value = userInfo.phoneNumber);
await page.$eval('#order_billing_address', el => el.value = userInfo.billingAddress1);
await page.$eval('#order_billing_address_2', el => el.value = userInfo.billingAddress2);
await page.$eval('#obz', el => el.value = userInfo.zipCode);
await page.$eval('#order_billing_city', el => el.value = userInfo.billingCity);
await page.select('#order_billing_state', userInfo.billingState);
await page.select('#order_billing_country', userInfo.billingCountry);
await page.$eval('#cnid', el => el.value = userInfo.creditCardNum); // this is a prepaid card with like 30 cents on it
await page.select('#credit_card_month', userInfo.creditCardMonth);
await page.select('#credit_card_year', userInfo.creditCardYear);
await page.$eval('#vvv-container > input[type=tel]', el => el.value = userInfo.cvv);
await page.click("#order_terms");
await page.$eval('#g-recaptcha-response', el => el.value = userInfo.gRecaptchaRes);
await wait(DELAY); // wait a little before button is clicked
await page.click("#submit_button");
await page.waitForSelector('#checkout-loading-message > span > span'); // let payment processing page load before checking
async function startSafeBot () {
const browser = await puppeteer.launch({
headless: false,
});
const browserPage = await browser.newPage();
const userData = {
'name': 'frank ied223213',
'email': 'frankied324234234@gmail.com',
'phoneNumber': '914-123-1234',
'billingAddress1': '123 testing lane',
'billingAddress2': '',
'zipCode': '12345',
'billingCity': 'test',
'billingState': 'NY',
'billingCountry': 'USA',
'creditCardNum': '12323123123123123213',
'creditCardMonth': '04',

'cvv': '123',
'gRecaptchaRes': "3e232d32cf4d34343d434132d4124c234d24"
};
await generateSupremeBrowser(browserPage,1,"beaded","Black","N/A");
await addToCart(browserPage);
await checkout(browserPage, userData);
await processPayment(browserPage);
await browser.close();
}
startSafeBot();
我尝试过先声明userinfo，然后为它分配值。没用另外，当我在
console.log("checkout loaded, filling payment...")个用户信息是使用我为其分配的所有值定义的。这很奇怪，因为它已经定义了。我相信这与木偶戏有关。我也尝试过让$ {userInfo.name}也不走运。
