Your logs show Puppeteer/Chromium failing with pthread_create: Resource temporarily unavailable, which occurs when the service's available memory is too low for Chromium to create new threads. Check the Metrics tab in your service to see if memory is maxing out, and if you have replica limits configured under Service Settings > Deploy > Replica Limits, ensure the memory limit is high enough for Chromium (it typically needs at least 1-2 GB).
