String?

I think I found out:

[Daniele B]

@Serializable
data class ApiResponse(
    @SerialName("data") val data : List<CovidRow>,
    @SerialName("err") val error : String? = null,
)

[Daniele B]

String? = null

thanks

[Javier]

So you need to indicate the default parameter?

[Daniele B]

yes, if I don’t write “= null” it gives an error, in case the response doesn’t include that field
