x.json2 error: Any has no variant VariantData

[Avey777]

Describe the bug

error: Any has no variant VariantData

Reproduction Steps

module main

import x.json2

type Any = string | int | bool | []string | map[string]int

fn main() {
	mut data_list := []map[string]Any{}

	mut item := map[string]Any{}
	item['key'] = 'value'
	item['another_key'] = 42
	item['yet_another_key'] = 425
	item['key1'] = 'value1'
	item['key2'] = ['d', 'g']

	data_list << item
	dump(json2.encode(data_list))
}

Expected Behavior

[map_any.v:38] json.encode(data_list): [{"key":"value","another_key":42,"yet_another_key":425,"key1":"value1","key2":["d","g"]}]

Current Behavior

Even this simpler case cannot proceed (tested in playground):

import x.json2

fn main() {
	mut data_list := []map[string]json2.Any{}
	mut item := map[string]json2.Any{}
	data_list << item
	dump(json2.encode(data_list))
}

type []map[string]json2.Any cannot be array encoded
[code.v:7] x.json2.encode(data_list): ["null"
