GPT Action response empty

[axel.hochstein]

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.
