Using Apify Puppeteer to extract news articles with pagination. A custom page function now triggers a ‘TypeError: context.enqueueRequest is not a function’ error. See revised code below:
async function processPage(info) {
const { reqObj, $, logger, pageInstance } = info;
await pageInstance.goto(reqObj.link, { waitUntil: 'domcontentloaded' });
// Check for articles published after 2024-08-15 and handle pagination
const nextLink = await pageInstance.$eval('div.next a', el => el.href).catch(() => null);
if (nextLink) {
await processPage({ reqObj: { link: nextLink }, $, logger, pageInstance });
}
return [];
}
I have encountered a similar issue during my recent upgrade of the crawler implementation. The error arises because the context object passed to your function no longer provides the enqueueRequest method. A solution that worked for me was to decouple pagination logic from the page function itself. I switched to gathering the URL of the next page and then leveraging the crawler’s external queue management to handle the new request. This method keeps the page function focused purely on processing content, while the crawler framework manages queuing, ultimately yielding more robust and maintainable code.
hey, try to use the reqQueue api directly, cuz context.enqueueRequest isn`t available now. i solved mine by keeping a reference to the queue and calling its addRequest method for pagination. give that a whirl, might just work better
I ran into a similar issue a few months ago while updating my scraping project. I discovered that the enqueueRequest function was being deprecated in favor of explicitly referencing the request queue provided by the crawler. My solution was to pass the queue instance down to the page function, so instead of attempting to enqueue inside the page logic, I managed pagination externally. This approach also simplified error handling and retries, making my code more robust when facing unexpected navigation behavior. Give this an approach if you’re updating to a newer version.
Updating my scraping routine exposed similar issues when moving to the latest Apify libraries. I resolved it by externalizing pagination handlers. Instead of trying to use a deprecated enqueueRequest method within the page function, I manage pagination in a separate controller that receives and processes new links from the page. This not only sidesteps the recursion error but also offers better error handling and clearer code structure. I recommend passing the explicit queue object to your functions and using its addRequest method to manage pagination requests.
I have encountered a similar issue previously while updating my project to the latest Apify library versions. The error indicates that the function context.enqueueRequest is no longer available in your current setup, likely because the object you are passing to processPage does not have full crawler context. In my case, I resolved it by explicitly managing the request queue outside the page function and using the official addRequest method on the request queue instance. This way, I ensured that pagination works properly without recursing into a non-existent function.
