handle errors

The React team believes that server-side errors should be handled in the second then argument. But if an error occurs (an error in our logic) in the first argument of then, it will not be caught. So you think that logic errors should be caught elsewhere (maybe Error Boundary)?

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(json => {
     console.log(json)
     throw new Error('myError') // <= Error here
  },  
    (error) => {
       console.log(error) // <= do not work
    }).catch(error => console.log(error)) // <=  work

Start with the fetch example in the issue and compare the second then argument with catch and React Error Boundaries. Confirm how errors thrown in the first callback propagate, then identify the relevant React documentation page and define the issue as resolved once the guidance clearly explains where each kind of error is handled.
