I need help with basic stuff again… I think the question is essentially, why can I not send and receive JSON?

ITT client-side error

192.168.2.250:54636 - "POST /itt HTTP/1.1" 422 Unprocessable Entity

ITT server-side error

        print('itt', file=sys.stderr)
        context = json.loads(data)

        result :AsyncIterator[str] = _itt(client, context) # TODO await ?
        return StreamingResponse(result)

the STT error

I think the ones below here are working, but I’m getting an illegal instruction during encoding. Computer unfixably old probably.

    # text-to-speech client
    response = requests.get(url, params={'prompt':mesg}) # TODO headers ?
    print('sent_to_server', file=sys.stderr)
    if response.status_code != 200:
        print('error', response, file=sys.stderr)
        return
    print('ok_to_server', file=sys.stderr)
    content = json.loads(response.content)
    audio:ndarray = np.array(content)

    # text-to-speech proxy
    @app.get("/tts")
    async def tts(prompt:str)->Response:
        print('tts', prompt, file=sys.stderr)
        response = requests.get(host2, params={'prompt':prompt}) # TODO async ? # TODO headres ?
        return Response(response.content)

    # text-to-speech server
    @app.get("/")
    async def tts(prompt:str, name:str="en_speaker_9")->Response:
        print('received', file=sys.stderr)
        audio_array:ndarray = generate_audio(prompt, history_prompt=name) # TODO no async ?
        content = audio_array.tolist()
        print('generated', file=sys.stderr)
        return Response(json.dumps(audio_array))
