npm run dev

client:

npx tsx src/rpc/client.ts

What is the expected behavior?

For the request to be processed and end correctly and the program to exit.

The request hangs indefinitely

Additional information

It works with an Effect.ts powered HTTP server along the lines of:

export const RpcLayer = RpcServer.layer(MinimalPingRpc).pipe(
  Layer.provide(MinimalPingLive),
)
export const RpcHttpProtocolLayer = RpcServer.layerProtocolHttp({
  path: '/api/rpc',
}).pipe(Layer.provide(RpcSerialization.layerJson))

const Main = HttpRouter.Default.serve().pipe(
  Layer.provide(RpcLayer),
  Layer.provide(RpcHttpProtocolLayer),
  Layer.provide(BunHttpServer.layer({ port: 3000 })),
)
BunRuntime.runMain(Layer.launch(Main))
