No 'Access-Control-Allow-Origin' header is present on the requested resource.

Hi!

I have my own openai compatible endpoint that works fine in all my programs
i.e. in python:

import openai
client = openai.OpenAI(
    api_key="my-key",
    base_url="http://***.111:80/v1"
)
with open("./tracks/test.ogg", "rb") as audio_file:
    transcript = client.audio.transcriptions.create(
        file = audio_file,
        model = "whisper-1",
        response_format="srt",
    )
print(transcript)

So endpoint works fine.

But when I try to put it as API_URL I keep getting network error message in logs

Access to XMLHttpRequest at 'http://***111/v1/audio/transcriptions' from origin 'app://obsidian.md' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Thing that confuses me is the error message contain no port info. Is it normal?

I've tried putting all cersions:

• http://***.111:80/v1/audio/transcriptions
• http://***.111:80/v1
• http://***.111:80
  Non of them proved to be working

I saw in other issues (i.e. #2) that changing endpoint works well.
What I'm doing wrong?

Yeah thanks, this solved my issue. If your custom openai compatible endpoint is in nodeJS, for example, add CORS to your response headers like:

new Response(
    JSON.stringify(data),
    { headers: { 
      "Content-Type": "application/json",
      "Access-Control-Allow-Origin": "*", // or specify a particular origin
     } })

might make a difference.
