Correction of the error in the parser operation on VPS
45 USD The positions are not updating for certain links, the donor is the same, some links work and some do not. I tried to check if the names of the links and the link itself have changed, and this did not succeed, the links have not changed. It is necessary to find and fix the error for stable link updates.

Hello, Captain! The situation is typical for parsing: if some links from one donor work and some do not, the problem usually lies not in the address (URL) itself, but in the structural differences of the pages or the donor's protection. Since we have already worked with your export scripts, I suggest conducting a deep debug to find the "weak spot."
🔍 Possible reasons for failure (that I will check):
1. Different card layouts: On the same website, products from different categories (or with different statuses, such as "Out of stock") may have a different HTML structure. The script simply does not see the price where it is used to looking for it.
2. Dynamic content (JS): Some pages may load the price through scripts (JavaScript) with a delay. The standard parser sees an empty field, while the browser shows the price.
3. Anti-bot protection (Rate Limiting): The donor may selectively block requests. If the links are consecutive, at a certain iteration, the protection (Cloudflare/Captcha) triggers, and the subsequent links return a 403 or 404 error.
4. Redirects: Sometimes the link visually has not changed, but the server performs an internal redirect, where session or authorization data "gets lost."
🛠 My action plan:
• Response logging: I will add extended logging to the script for problematic links. We will see what exact HTML code the bot receives at the moment of the request.
• Selector validation: I will check if the classes or IDs have changed specifically on those pages that "failed."
… • Browser emulation: If the problem is in the protection, I will set up more random User-Agents or proxies so that the donor does not recognize the bot.
• Exception handling: I will add a check script: if the price is not found by the main selector, search by an alternative.
Can you send 2-3 examples of links that are currently not updating and 1 that is working? I will instantly compare their code and tell you what the difference is. Ready to start fixing right now!

Good day. I would like to take a look at the parser itself. What language is it written in? I can only help if it is Python.

I will be able to connect and quickly find out why some links from one donor are updating while others are not. I will understand the logic, check where the processing is breaking, and bring it to stable updates.
Question: Is this a parser/script in Python, and can you provide examples of 2-3 working and 2-3 non-working links for testing?
