I'm trying to deploy a SvelteKit starter app to Cloudflare using the cloudflare documented method. The following is embedded in the larger build output on Cloudflare's Pages server.
2023-01-08T09:01:19.786481Z npm ERR! code ELIFECYCLE

2023-01-08T09:01:19.787326Z npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
After googling, I've found a few places that talk about a similar error - but it seems that all of the mentioned cases are specific to running the app locally. I can run the SvelteKit app fine locally. Only at deploy time do I get these errors. I set both my local nodejs and Pages nodejs versions to 16 in the environments as suggested in the documentation.

This was my own oversight. I incorrectly set the NODE_VERSION for the "preview" profile and not for the "production" profile. Actually - I'm not sure how to execute the preview profile, but in either case for what it's worth - pay close attention to which profile's environment variables you are setting within the Cloudflare settings dialogue.
