How do I get a JSON list/array using Ktorfit?

[LionZXY]

Background

I have a some object, for example:

data class Person(val name: String)

And some API that returns an array of these Person:

[{"name": "John"}, {"name": "Alex"}]

Question

When I use the pure ktor api I can use this API like this:

val response = client.get("https://persons.example/getAll").body<List<Person>>()
println(response)

Result: [Person(name=John), Person(name=Alex)]

When i use retrofit i can use this API like this:

interface PersonApi {
    @GET("getAll")
    suspend fun getPersons(): List<Person>
}

val response = personApi.getPersons()
println(response)

Result: [Person(name=John), Person(name=Alex)]

BUT
When i try use ktorfit with same interface like retrofit, with same ktor HttpClient, i receive this error:

Caused by: kotlinx.serialization.json.internal.JsonDecodingException: Expected start of the object '{', but had 'EOF' instead at path: $

Hi, it should work that way. Are you setting the right baseUrl? Are you getting a response with:

suspend fun getPersons(): String ?

Yes
Yes, you can try adding a method in your example that returns an array and it won't work either

You can try running the android example from here:
https://github.com/LionZXY/Ktorfit/tree/array_application
And look at this code:
https://github.com/LionZXY/Ktorfit/blob/array_application/example/AndroidOnlyExample/app/src/main/java/de/jensklingenberg/androidonlyexample/MainActivity.kt#L64-L71

// Loaded successful:
val response = api.getApplicationsString()
Log.i("MainActivity", response)
// Decoded successful:
val decodedAnswer = json.decodeFromString<Array<KtorfitApplicationShort>>(response)
Log.i("MainActivity", decodedAnswer.toList().toString())
// Crash:
peopleState.value = api.getApplications().firstOrNull()

Thank you for the example project, i can reproduce the issue, its a bug. A workaround is to wrap it in a Response Response<Array> . Im planning to fix the bug today
