Rollup proxy configuration causes the short circuit in the client-server

Question

In my rollup.config.js file, I have added the following lines to proxy the requests destined to the client-server to the backend as such:

!production && localdev({
  dirs: ['public'],
  host: 'localhost',
  port: 9876,
  proxy: [{ from: '/api/*', to: 'localhost:8080' }],
}),

, but this causes the server to short circuit and give the prompt below:

yarn run v1.22.11
warning package.json: No license field
$ rollup -c -w
rollup v2.58.0
bundles src/main.ts → public\build\bundle.js...
LiveReload enabled

Done in 3.63s.

it should be working until it is explicitly interrupted, though.

Answer 1

change localhost:8080 to http://localhost:8080. it's bad that it doesn't shout the error.
