Forms of array elements in node and express

Question

Despite all my efforts, I was stuck in getting array keys for form elements introduced in NodeJS, Express, and handlebars.

The elements of my form are as follows:

{{#each block}}
<input type='text' name='block_payout[{{id}}]' />
{{/each}

This results in the following markup in the browser:

<input type='text' name='block_payout[14]' />
<input type='text' name='block_payout[15]' />
<input type='text' name='block_payout[16]' />

In PHP, this will lead to the array as an element of the $ _POST array:

$_POST [
  block_payout [
    14 => value1
    15 => value2
    16 => value3
  ]
]

However, the req.body property in Node / Express removes these keys and creates an indexed array:

req.body [
  block_payout [
    0 => value1
    1 => value2
    2 => value3
  ]
]

Since I want to use the key to bind the presented values ​​to something else, for me this is a big problem. Does anyone know how I can get the provided form data with the correct keys?
