[FIXED] com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type from String: not one of the values accepted for Enum class

Issue

I'm upgrading a Spring Boot web service from Kotlin 1.4.32 to 1.5.0.

// Before:
kotlin("jvm") version "1.4.32"
kotlin("plugin.spring") version "1.4.32"

// After:
kotlin("jvm") version "1.5.0"
kotlin("plugin.spring") version "1.5.0"

After upgrading and running the API, I get the following error:

com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `models.SeasonType` from String "Season": not one of the values accepted for Enum class: [NO_SEASON, UNKNOWN, SEASON]

SeasonType is an enum class:

package models

import com.fasterxml.jackson.annotation.JsonCreator

enum class SeasonType(val value: String) {

    SEASON("Season"),
    NO_SEASON("NoSeason"),
    UNKNOWN("Unknown");

    companion object {
        @JsonCreator
        @JvmStatic
        private fun creator(serializedValue: String): SeasonType =
            values().firstOrNull { it.value == serializedValue } ?: UNKNOWN
    }

}

Why does deserialization fail after upgrading Kotlin?

Solution

I was able to resolve this issue by upgrading to Kotlin 1.6.x.
