No stacktrace sources in `denoflare serve`

When running a script via denoflare serve, error stracktraces don't have source file path:

Yes this is tricky. Denoflare bundles (and rebundles) your code and runs it in a permissionless worker by defaule, and the last time I looked into it (a while ago) it was impossible to send sourcemaps. Might be a good idea to look into it again and see if it's still the case.

You can run with --local-isolation none which will import your code directly, but you'll lose auto-reloading, and will run outside of the permissionless worker so will be able to access the fs etc (ie an environment less like cloudflare). https://denoflare.dev/cli/serve

Couldn't find code that is responsible for bundling but after https://github.com/denoland/deno/issues/11073 and general development of Fresh framework, esbuild is working really smooth with Deno. High confidence that source map should work with it.

Ah, I haven't considered that. I moved my side project to wrangler now because I wanted to make it happen ™, but will try it out in my next revision.
