Hi, does anyone know how to deserialise an enum from a string?

@Serializable
enum class Error(@SerialName("code") val code: String? = null) {
    UNEXPECTED("0001")
}

If I pass it a json string of the following I want it to create an enum response.

{
  "code": "0001"
}

I used to use CommonEnumSerializer but its been deprecated. Is there an alternative?

[Sean Keane]

Just a note, the reason I want this is because all the other examples show an enum nested in a data class. But all I need is the object

I had to create a custom deserializer to handle this

[Sean Keane]

Do you have an example by any chance? I was using the custom CommonEnumSerializer but I can't seem to use it with 0.20.0

This is for polymorphic serialization but if you amend it a bit it should work for you.

I'll give this a try! Thank you 👏

Ok, that didnt work for me so I decided to just use a filter.

Error.values().first { it.errorCode == "0001" }

What was the error it gave?

[Sean Keane]

I changed the approach as this was to merge two enums and return an interface, what I needed to do was construct an enum based on a param.

[Patrick]

How exactly did you solve it?

[Sean Keane]

return YOURENUMCLASS.values().first { it.errorCode == code }
