Hello, I have a JSON where the keys are the ids.

{
  "0": {"name": "John"},
  "1": {"name": "Jane"},
  "2": {"name": "Pete"},
  ...
}

I'm super new to the Serialization library, and I can't find which will be the best approach to deserialize it and have the id as part of the object? Something like this:

Person (id: Int, name: String)

Thank you🙂

It would be a Map<String, PersonDto> where the PersonDto has only the name.

[Paul Woitaschek]

Then you map that to a List<Person>.

[Paul Woitaschek]

You can also go with a custom serializer but implementing it like this will be way simpler and easier to maintain while also providing encapsulation

Awesome. I will try it. Thank you @Paul Woitaschek 🙏

Can it be that this does not work because the array of objects is not an array but an object?

{
  "0": {"name": "John"},
  "1": {"name": "Jane"},
  "2": {"name": "Pete"},
  ...
}

and not

[
  "0": {"name": "John"},
  "1": {"name": "Jane"},
  "2": {"name": "Pete"},
  ...
]

[hugo.matilla]

I'm receiving this error: Error kotlinx.serialization.json.internal.JsonDecodingException: Expected start of the array '[', but had 'EOF' instead

Use MapSerializer(String.serializer(), PersonDto.serializer))
