I’m trying to build a custom GPT and configure an action. I have a very simple YAML schema and it works when I call the endpoint in my browser:  
https://student\_tracker-1-u7838153.deta.app/test

The GPT Action returns only empty brackets {}.  
Here is the schema:

openapi: “3.0.0”  
info:  
version: 1.0.0  
title: Test  
servers:  
- url: https://student\_tracker-1-u7838153.deta.app  
paths:  
“/test”:  
get:  
summary: Root  
operationId: root\_\_get  
responses:  
‘200’:  
description: Successful Response  
content:  
application/json:  
schema:  
$ref: “#/components/schemas/Answer”

components:  
schemas:  
Answer:  
type: object  
properties:  
message:  
type: string

Anyone observing similar issues? Any ideas?

I have also encountered empty responses, and after testing, I found that it was due to the returned content containing garbled characters that are not in UTF8 (I am in the Chinese Big5 language system).

Thanks for your message. I noticed that I didn’t make my routes public on server side.
