Can anyone help me figure out why price price is displaying these extra numbers? I cannot figure this out

You need to parse it properly. Try the below code
export function extractPrice(...args: any){ for(const element of args){ const price = element.text().trim(); if(price){ return price.replace(/\D/g, ''); } } return ""; }

I am not able to get any mails in my inbox after submitting even after doing everything correctly

"use server";

LOWEST_PRICE: "LOWEST_PRICE",
THRESHOLD_MET: "THRESHOLD_MET",
};

export async function generateEmailBody(
product: EmailProductInfo,
type: NotificationType
) {
const THRESHOLD_PERCENTAGE = 40;
// Shorten the product title
const shortenedTitle =
product.title.length > 20
? ${product.title.substring(0, 20)}...
: product.title;

let subject = "";
let body = "";

switch (type) {
case Notification.WELCOME:
subject = Welcome to Price Tracking for ${shortenedTitle};
body = <div> <h2>Welcome to PriceWise 🚀</h2> <p>You are now tracking ${product.title}.</p> <p>Here's an example of how you'll receive updates:</p> <div style="border: 1px solid #ccc; padding: 10px; background-color: #f8f8f8;"> <h3>${product.title} is back in stock!</h3> <p>We're excited to let you know that ${product.title} is now back in stock.</p> <p>Don't miss out - <a href="${product.url}" target="_blank" rel="noopener noreferrer">buy it now</a>!</p> <img src="https://i.ibb.co/pwFBRMC/Screenshot-2023-09-26-at-1-47-50-AM.png" alt="Product Image" style="max-width: 100%;" /> </div> <p>Stay tuned for more updates on ${product.title} and other products you're tracking.</p> </div>;

I am getting error 503 when I try to scrape a product. Anyone else dealing with this?

=> Already connected to MongoDB

Did you find a solution I am experiencing the same problem right now. It worked the first time, but now I get a 503 error.

Not yet, I will post one here if I find it, or maybe someone will post one here when they find it.

Alright thanks, he mentions in the video that it may not work during development when you are using a localhost, so I am hoping that is what is going wrong and it works in production.

i got its solution. it might be due to the imgUrls it was returning.

image: imgUrls[0]||productImg,

changing to this line helped solve the error

Brother where do you change that line?

After deployment, how can the public open the website? I tried opening the link and it says I am not a member of the team and therefore cant view the page.
