this is my Json input

[Tóth István Zoltán]

Which library do you use for Json serialization/deserialization? Also, is this error from the client or the server side. This is most probably a de-sync between the server and the client side definition.

[Praveen Kumar]

implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.5.1")

am using this library for serialization

[Praveen Kumar]

are u saying it's a backend issue?

[Aleksei Tirman [JB]]

Can you share the code where the HTTP request is being made?

[Praveen Kumar]

class GetProductsUseCase: BaseUseCase<String, ArrayList<Engine>>() {
    override suspend fun execute(plant_id: String): ArrayList<Engine> {
        val response = <http://networkClient.post|networkClient.post>("<https://cmms.auswegprime.com/Api/get_plant_engineer_status_list>")
        return response.body()
    }
}

here

[Aleksei Tirman [JB]]

The problem is that you're trying to receive an ArrayList but the JSON's root element is an object.

[Aleksei Tirman [JB]]

So either the JSON's root element must be an array or you have to change what is being received.

[Praveen Kumar]

class GetProductsUseCase: BaseUseCase<String, List<Engine>>() {
    override suspend fun execute(plant_id: String): List<Engine> {
        val response = <http://networkClient.post|networkClient.post>("<https://cmms.auswegprime.com/Api/get_plant_engineer_status_list>")
        return response.body()
    }
}

now, its right?

[Aleksei Tirman [JB]]

You can check whether it's right or wrong by running the application.
It seems like it's still wrong. Please read the documentation or some tutorials on the kotlinx.serialization framework to get a better understanding of how the mapping works.

[Praveen Kumar]

@Aleksei Tirman [JB] okay, are you doing any freelancing for KMM?

[Andromadus Naruto]

@Praveen Kumar you'll need to wrap your List<Engine> within a data class with a property named data

Example:
data class ApiResponse<T>(
val iserror: Boolean,
val message: String,
val data: T,
)

class GetProductsUseCase: BaseUseCase<String, List<Engine>>() {
    override suspend fun execute(plant_id: String): List<Engine> {
        val response = <http://networkClient.post|networkClient.post>("<https://cmms.auswegprime.com/Api/get_plant_engineer_status_list>")
        return response.body<ApiResponse<List<Engine>>>().data
    }
}
