Cannot resolve nested path with snowpack

Question

In my react project a hard refresh of a nested path does not work. Then snowpack config tries to load from the folder "dist" and cannot serve the page.

config like in snowpack docu:

{
  mount: {
    public: '/',
    src: '/_dist_',
  },
   ...
 }

error

http://localhost:3000/myfolder/id

GET http://localhost:3000/myfolder/_dist_/index.js net::ERR_ABORTED 404 (Not Found)
