Cloudflare worker builds run out of memory when attempting to generate/upload sourcemaps

[saturnonearth]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

When attempting to build my SvelteKit project on Cloudflare Workers, I am getting a Javascript heap memory error. The build works fine locally.

Building will Rolldown appears to work, but I experience other issues related to the meta-framework so this is currently not a viable solution.

Expected Result

The build should work as intended.

Actual Result

Javascript heap error, crashes build.

Hi @saturnonearth, thanks for filing this issue.

Unfortunately source maps generation is a costly process. Could you try to up the runner's memory allocation and see if this alleviates anything?

Typically via setting NODE_OPTIONS=--max-old-space-size=8192. Does that help?

This actually did fix the issue! I am very surprised that a setting like this is not mentioned by Cloudflare

I think this issue can be closed then :) Good to hear that it worked for you this way.
