I am sorry, I had unintentionally changed the v-field's name attribute from 'drink' to 'drink[]'. Can you just try it with changing attribute from 'drink[]' to 'drink'?

thanks, the fix should be tagged in 4.1.20

I am afraid, but another bug is introduced. To reproduce the bug,

• Change the v-field's name attribute from 'drink[]' to 'drink'
• Change the initial value from [2] to [3]
• Click the submit button
• Output will be

{
  "drink": [
    3,
    [
      3
    ]
  ]
}
