How can I make Promise.reject (res.text ()) return text instead of [object promise]?

  With this code

  .then (res = & gt; res.ok? Res.json (): Promise.reject (res.text ()))

  
  [object promise] is returned to return the error text, I have to do this:
  

  .then(res => res.ok ? res.json() : res.text())
  .then(res => if (res !== undefined) return Promise.reject(res))
  .catch(e => `Ошибка: ${e}`);

  
  tell me, can't you do it differently?
  And another question:
  

  .then(res => res.json())
  .then(res => res.users)

  
  why not return users immediately, like this?

  .then (res = & gt; res.json (). users)

  the answer gave you in the previous question along with an example

  Because this is the specification of the method.
  
  

  Body.json ()
  
  Takes a Response stream and reads it to completion. It returns a promise that resolves with the result of parsing the body text as JSON, which is a JavaScript value of datatype object, string, etc.

  No way. Promise.reject - Returns a promise .

  Rewrite your code using async / await and then instead of promises you can get the result immediately.
