774-781: Consider adding more specific error handling.In the catch block for the dispatch event with navigation, you're catching a generic error but not logging its specific details. This could make debugging more difficult in production.
} catch (dispatchNavError) { try { await button.click(); await page.waitForTimeout(2000); } catch (clickError) { + debugLog(`Click error after dispatch failure: ${clickError.message}`); await button.dispatchEvent('click'); await page.waitForTimeout(2000); } }

732-741: Great addition of content signature tracking.The new
captureContentSignaturefunction smartly captures the URL, item count, and first few items before pagination, which will help reliably detect content changes even when the URL remains the same.
743-744: Good improvement to logging.Capturing the item count before clicking provides valuable debugging information and will make it easier to track pagination progress.
729-746: Better naming withpaginationSuccessvariable.Renaming from
navigationSuccesstopaginationSuccessmore accurately reflects the operation being performed, improving code readability and maintenance.
760-783: Robust enhancement to click handling.The addition of a fallback mechanism using
dispatchEvent('click')when the regular click fails is an excellent way to improve reliability. Some websites have complex event handling that might block regular clicks but respond to dispatch events.
787-804: Comprehensive page change detection.The change detection now checks multiple indicators (URL change, content change, item count change) which will make pagination more reliable across different website implementations.
806-807: Improved error logging.Including the error message in the log makes debugging much easier, especially for intermittent pagination issues.
818-820: Enhanced failure reporting.Adding a specific log message for pagination failure helps with debugging and understanding when the scraper has stopped due to pagination issues rather than other errors.
812-813: Clear retry attempt logging.Including the current attempt number and maximum retries in the log message provides better context for debugging pagination issues.
