Impossible to set timeout globally

[t-sakharova]

I want to set timeout for all requests, so I use httpConfig

const httpAdapter = new HttpAdapter({
  httpConfig: {
    timeout: 3000
  }
})

But this doesn't work, maybe because of this line?

I can pass config to all methods (create, update, etc) and it works, but I want to do it in one place
