Internal Server Error when we do “too much” on the Printful side

## What Happened

If we create a few new products or change a few mockup images, it seems to crash the store for some amount of time.

## Expected Behavior

We can create away on the Printful backend without crashing things.

## Steps to Reproduce

1. Make sure the store is up
2. Change a bunch of stuff on Printful (e.g. mockups or add products)
3. See the site crash
