In my app https://glitch.com/~emoji-gender-reveal, my cron job that hits it has been timing out because waking up the app takes so long. Looking at the logs, the project reinstalls all the dependencies, which adds a huge amount of overhead to the wake up process.
Why is this happening? If the package-lock.json file hasn’t changed since the last run, why does everything have to be reinstalled? Is it something in my project that is misconfigured?
Here are the logs from waking it up a few minutes ago:
