swc tsCompiler does not seem to do anything

[EdwardKerckhof]

Steps taken:

1. Create fresh nestjs application
2. Add @swc/core to dev dependencies
3. Create vite.config.ts
4. Update src/main.ts

Error:

vite.config.ts

src/main.ts

When removing the tsCompiler option I get the same error, but I was under the impression swc would fix reflect-metadata doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix.
