Python-slack-sdk: Slack Login Error in rtm_connect

[LMPK]

I am following this tutorial here: https://www.fullstackpython.com/blog/build-first-slack-bot-python.html and I am having a problem when I am trying to run the code. The errors I get are:

Traceback (most recent call last):
File "C:\Users\n0342338\AppData\Local\Programs\Python\Python36\lib\site-packages\slackclient\client.py", line 52, in rtm_connect

When I started with this same code, I got the same SlackLoginError in the same files and lines. The issue I had was handing the wrong token along. It took me a while to figure out what I was supposed to do too, but I found it. You need to use the Bot User OAuth Access Token specifically (see below).

This got my bot to deliver the Starter Bot connected and running! text properly.

[sharad-vm]

I got the bot user access token right and set it to an environment variable but, I still get the same error.
I'm on a Windows machine. Maybe this is an issue on Windows?

[clodoan]

I'm having the same error! Have you already found the solution for this? Thanks!

[aoberoi]

@clodoan are you also on Windows? can you check to see if the slack_token variable has the right token value? i would do this by putting print(slack_token) right after the first line.

[clodoan]

thanks @aoberoi ! I've just found the error: I was using a method that doesn't work with bot token. Just with user token or workplace token! Thanks anyway 👍 !

Hi, same error on mac--> i have used correct token--> but same error: Any suggestion plz

[saurabhbahl19]

I tried using bot token still it is failing.
I am using python3 , i also python 2 installed.

[saurabhbahl19]

OK I fixed the issue , rather than using pybot token use user token . it
worked for me.

[w-red-1]

python2 starterbot.py worked for me with the Bot User OAuth Access Token

[jimmy927]

This still seems to be an issue.

If i connect with the xoxp-* token i get: not_allowed_token_type
If i connect with the xoxb-* token i get: The server responded with: {'ok': False, 'error': 'missing_scope', 'needed': 'rtm:stream' [...]

I have given the app all permissions possible.

Using this example-code:

import os
import slack

@slack.RTMClient.run_on(event='message')
def say_hello(**payload):
    data = payload['data']
    web_client = payload['web_client']
    rtm_client = payload['rtm_client']
    if 'Hello' in data.get('text', []):
        channel_id = data['channel']
        thread_ts = data['ts']
        user = data['user']

        web_client.chat_postMessage(
            channel=channel_id,
            text=f"Hi <@{user}>!",
            thread_ts=thread_ts
        )

slack_token = os.environ["SLACK_API_TOKEN"]
rtm_client = slack.RTMClient(token=slack_token)
rtm_client.start()

EDIT This however works with a old xoxb-* legacy-token.

[stevengill]

@jimmy927, the new granular scopes (new xoxb-* token) don't support RTM. You can create a classic slack app if you need to create a new token. But keep in mind that the Slack App Directory will stop accepting new app submissions for classic slack apps on Feb 21, 2020.

Instead of RTM, we recommend using the Events API. If there is a specific reason or use case you need RTM over Events API, I'd love to hear about it.

I see. I think that event-API looks good it solves some problems, but at additional complexity. To set up a lot of different endpoints in my app is just much more work and more complex when i just need to build a simple chatbot that responds to some simple commands. Also you assume i have some app somewhere that can receive your calls.

[stevengill]

@jimmy927 I understand the issue about having to spend time updating an app that already works for you.

If you aren't distributing your app to the App Directory, you can continue to use RTM. Just use the Classic Slack App as I mentioned above.

Events API does need some sort of backend to receive events and handle posting to a channel.

I am actually migrating from python slackclient 1.x, and according to the migration guide i should use RTM, see here: https://github.com/slackapi/python-slackclient/wiki/Migrating-to-2.x

However i am now following this guide instead.

https://medium.com/@ronakbansal/how-to-build-slack-bot-with-python-django-using-events-api-670460930172

I do have an backend that is reliable, i just think you should keep it simple, keep in mind i have written different slack-integrations for half a decade and i am confused which API to use.

I think your new mechanics is too complex for a beginner to get started.
Imagine i would have to write this without the blogpost above, it would probably take me an entire day to get everything working and understand the mechanics.

[stevengill]

@jimmy927 thanks for pointing out that the migration guide is using rtm. I will file an issue to get that updated.

That guide on medium looks useful. I'd also recommend checking out our python tutorials on GitHub. These have been recently updated to use events instead of RTM since the granular scopes changes.

We are also investing time in creating more tutorials for python specifically. We know that we don't have enough examples and plan on providing more in the near future so it is easier and faster for folks looking to get started and for folks looking to dive deeper into app building.

Looks great, but it uses Flask which i don't have or want to introduce on my side.
