reflect-metadata on Deno Deploy not working?

Is there a reason why no reflect-metadata-libs work on deno deploy?

I have tried the following:
- https://www.npmjs.com/package/@abraham/reflection
- https://deno.land/x/reflect_metadata@v0.1.12-2
- https://deno.land/x/deno_reflect@v0.2.1
- https://deno.land/x/reflection@0.0.2

npm
