Fix Puppeteer Chrome launch error on ARM server
Analyzed the error 'Syntax error: Unterminated quoted string' when launching headless Chrome on an ARM server. Traced root cause to Puppeteer downloading an x86_64 Chrome binary because it maps linux_arm to linux64. Also found that env('PUPPETEER_EXECUTABLE_PATH') returns null in production due to Laravel config caching, causing the custom executable path to be ignored. Fixed by moving the environment variable into a config file and using config() instead of env(), then clearing the config cache. User confirmed the fix resolved the issue.
outcome
The Puppeteer launch error is resolved by using config('auctionbot.puppeteer_executable_path') to read the path to system Chromium and clearing the config cache.

key decisions
- Use config() helper instead of env() for PUPPETEER_EXECUTABLE_PATH to avoid null returns when config is cached.
- Point Puppeteer to the system-installed Chromium binary at /usr/bin/chromium-browser rather than relying on the downloaded x86_64 build.

Investigate and plan fix for inaccurate close_at values
Investigated why lot close_at values are sometimes near-current time despite lots having significant remaining time. Found that the scraper reads a client-side countdown text, which may show placeholder values before JavaScript updates, and that timezone differences (headless Chrome in UTC vs Laravel in America/Chicago) cause offset errors. Identified that the page exposes window.sam.serverData.secondsLeft with exact remaining seconds. The assistant created a detailed plan to modify the Puppeteer script to extract secondsLeft and inject it as a hidden DOM element, then update the PHP parser to read this marker. The plan was accepted by the user but execution was interrupted before any code changes were made.
outcome
A detailed plan to use secondsLeft exists but no code changes have been applied yet.
next steps
- Modify Scraper.php to add JavaScript that extracts window.sam.serverData.secondsLeft and injects a hidden marker element with data-seconds-left attribute.
- Modify Lot.php processLotState() to check for the marker and compute close_at by adding seconds to now(), falling back to existing parsing if marker absent.
- Deploy and test with debug logging to verify accuracy.
key decisions
- Use window.sam.serverData.secondsLeft as the primary source for remaining seconds instead of parsing countdown text.
- Inject a hidden <div> element with id 'auctionbot-seconds-left' and data-seconds-left attribute for PHP to read.
- Keep existing string parsing as fallback for pages without the secondsLeft data.
open questions
- Is window.sam.serverData.secondsLeft reliably available on all lot pages?
- What is the correct fallback behavior when secondsLeft is missing?
- Does the injected marker interfere with any page styling or behavior?
