What is 'Received a response in a non-JSON format' in chat.update

Nagisa1002 opened this issue 4 months ago · 3 comments

The error occurs in chat.update, but I can't find the cause.
Even if I enter the same text, it may not occur.

code:
The streaming output is reproduced on slack by rewriting the text output in token units from LLM using chat.update every 5 seconds.

temp_response = say('generating...', thread_ts=thread_ts)
    ch, ts = temp_response['channel'], temp_response['ts']
    last_update = -1
    for text in generator:
        if (time.time() - last_update) > 5.0 and text.strip():
            last_update = time.time()
            slack_bolt_app.client.chat_update(
                channel=ch, ts=ts, text=text)
            last_post_text = text

    if last_post_text != text:
        slack_bolt_app.client.chat_update(channel=ch, ts=ts, text=text)

error:

Hi @Nagisa1002, thanks for asking the question.

I guess the "text" argument you pass to the method may not be a string. If that's the case, your request to chat.update API could be invalid. I would recommend double-checking the "text" data provded by the "generator". If it's not a string, you need to build a string data before passing it. Also, enabling debug-level logging may help you out. You can add the following lines of code before the code you're investigating:

import logging
logging.basicConfig(level=logging.DEBUG)

I hope you will figure the cause out soon!
