Kong Custom Plugin Development: is it possible to have a configuration field with 2 types? How?

I'd like to know if it's possible to have a Kong custom plugin with a configuration field which can have one of these two different types: string or array. And in case it's possible, I'd like to know how.

Example usage (with Kubernetes Ingress Controller):

• with a single string:

  apiVersion: configuration.konghq.com/v1kind: KongPluginmetadata:  name: my-plugin-example  annotations:    kubernetes.io/ingress.class: kongplugin: my-pluginconfig:  different_types: |    value1    value2    value3

• with an array of strings:

  apiVersion: configuration.konghq.com/v1kind: KongPluginmetadata:  name: my-plugin-example  annotations:    kubernetes.io/ingress.class: kongplugin: my-pluginconfig:  different_types:    - "value1"    - "value2"    - "value3"

Here's what I tried (file schema.lua):

local typedefs = require("kong.db.schema.typedefs")local PLUGIN_NAME = "my-plugin"return {  name = PLUGIN_NAME,  fields = {    { consumer = typedefs.no_consumer },    { protocols = typedefs.protocols_http },    { config = {      type = "record",      fields = {        { different_types = {          description = "This is a config parameter with flexible type",          one_of = {             { type = "string" },            { type = "array", elements = { type = "string" },},          },          required = false,        },}      },    },},  },}

However, I'm getting error type = "required field missing":
