I had a this issue when attempting npm run serve (the default command for production environment with their Docker configuration). In my case, the .env was missing a HOST field.

Shopify Docs say HOST is required. This was tricky to diagnose because:

1. Shopify doesn't create a HOST field in the env by default
2. Shopify doesn't parse/validate the ENV up front
3. Shopify's error message directs developer to a node_modules file
4. Shopify renames HOST to hostName in their code
