I have this simple class that I use as a model for a a GET call with ktor ``` Serializable data class MeasurementsEndpoint SerialName measurements val measurements List lt Measurement gt SerialName measurementGroups val measurementGroups Map lt String MeasurementGroup gt ``` the call is made like so `http get lt MeasurementsEndpoint gt ` nothing fancy here but for some reason I get the error gt kotlinx serialization MissingFieldException Fields measurements measurementGroups are required for type with serial name no beiningbogen snute sharedlibrary library model endpoint MeasurementsEndpoint but they were missing When I test my request locally I don t get this error it only happens when I run the request from android or iOS clients Any idea what I m doing wrong

@Serializable
data class MeasurementsEndpoint(
    @SerialName("measurements")
    val measurements: List<Measurement>,

    @SerialName("measurementGroups")
    val measurementGroups: Map<String, MeasurementGroup>,
)

the call is made like so

http.get<MeasurementsEndpoint>(…)

nothing fancy here, but for some reason I get the error

kotlinx.serialization.MissingFieldException: Fields [measurements, measurementGroups] are required for type with serial name ‘no.beiningbogen.snute.sharedlibrary.library.model.endpoint.MeasurementsEndpoint’, but they were missing

When I test my request locally I don’t get this error, it only happens when I run the request from android or iOS clients. Any idea what I’m doing wrong?

Could you please share a request example that is made from Android or iOS?

I found that the error was due to wrong query parameters in my requests. Somehow the error message was telling the root object had an issue when it really was one of the nested object
