Bot Skill returning output to Power Virtual Agent import error

There's a trivial Bot Skill, built with Bot Framework Composer, which produces an Output to be returned back to the PVA Topic. The overall goal is to retrieve from the user a four digit number through its telephone (Dual Tone Multi Frequency) that's why using a skill to extend the PVA Topic. While importing the Skill on Power Virtual Agent I am getting this error:

Validation Code :MANIFEST_MALFORMED_DEFINITION_MISSING

Can you help me spot what is wrong?

Through Dialog Interface I defined an Ouput_0 of type string:

The skill asks the user an input of four digits, stores it in dialog.result.Output_0 and prints the 4 digit pin.

Tested succesfully the behaviour on BFComposer, published on Azure the skill but when uploading the skill to PVA there's an error: [Validation Code :MANIFEST_MALFORMED_DEFINITION_MISSING] while importing the skill:

here is the manifest:

{
 "$schema": "https://schemas.botframework.com/schemas/skills/v2.2/skill-manifest.json",
 "$id": "BotPinNumber-72a9e258-ee3e-4777-b062-ad6a5b07cba5",
 "endpoints": [
 {
 "protocol": "BotFrameworkV3",
 "name": "BotPinNumber",
 "endpointUrl": "https://BotNumberDialog.azurewebsites.net/api/messages",
 "description": "<description>",
 "msAppId": "ccde4b09-f8a7-5b08-b02b-98e25cc60402"
 }
 ],
 "name": "BotPinNumber",
 "version": "0.5",
 "publisherName": "PC",
 "activities": {
 "BotPinNumber": {
 "type": "event",
 "name": "BotPinNumber",
 "resultValue": {
 "type": "object",
 "properties": {
 "Output_0": {
 "type": "string",
 "title": "Output 0"
 }
 }
 }
 }
 }
}

Removing the skill output parameter Output_0 the error disappears, but obviously to my knowledge this is the only way a skill can return a result to the PVA Topic. Any hint would be really appreciated.
