This issue may occur due to poor network conditions or slow server responses. If the data hasn’t finished loading before the scraping tool starts parsing, the web scraper may mistakenly assume that no new content remains and stop scrolling, resulting in incomplete data extraction.
How can this be resolved?
One solution is to increase the delay time. First, observe how long a complete scroll typically takes, then set a slightly longer delay value to allow sufficient buffer time for the data to load completely.
Additionally, when dealing with large volumes of data, incomplete scraping may still occur. For example, if scraping 1,000 entries, the first 999 might succeed, but a sudden network delay at the 1,000th entry could cause the scraping to halt immediately.
To improve stability, set a delay time that is neither too short nor too long, balancing reliability and efficiency. This ensures smoother and more consistent data extraction.
