I'm trying to deserialise a json string as enum but it is always null. Although the same model works when I replace

@SerialName

with

@SerialisedName

from gson for the enum values. Also, it works when I change the enum name to all lower case which matches the response value. Any ideas what I'm doing wrong?

@Serializable
data class Colours(
    @SerialName("palette")
    val palette: Palette,
    @SerialName("theme")
    val theme: ColoursTheme = ColoursTheme.White
)

@Serializable
enum class ColoursTheme {
    @SerialName("white")
    White,

    @SerialName("bold")
    Bold,

    @SerialName("black")
    Black,

    @SerialName("accent")
    Accent
}

This is the JSON:

{
	"colours": {
		"theme": "accent",
		"palette": {
			"primaryHex": "#537e66",
			"secondaryHex": "#f3f3eb",
			"accentHex": "#537e66"
		}
	},
}

What do you mean, it is always null? In your data class,

val theme: ColoursTheme

is not nullable

yeah but the object i get is

Colours(palette = paletterObj, theme = null)

which is strange.
