Legacy bot was deprecated by Slack

[timur-ND]

Hello. Seems Slack Dev team deprecated bots https://api.slack.com/changelog/2024-09-legacy-custom-bots-classic-apps-deprecation
In your docs, you suggest to use bot user https://api.slack.com/legacy/enabling-bot-users

Old bot unable to connect to Slack API, got this error:

curl -H "Authorization: Bearer $SLACK_API_TOKEN" https://slack.com/api/auth.test

{"ok":false,"error":"legacy_custom_bots_deprecated","context":"Legacy custom bots has been deprecated on March 31st, 2025. Please create a new app using our updated methods. More info can be found in our changelog: https:\/\/api.slack.com\/changelog\/2024-09-legacy-custom-bots-classic-apps-deprecation"}

Now, I've recreated Bot, but as App Type - Modern. After configuration according to your docs, Memod is not working. Integration was added to channels, but I don't see logs about accepting messages or something. It looks like it doesn't listen.

I see in logs errors about reading user, but it was added to scope:

    bot_token = "xoxb-9***"

    [grafana]

    api_url = "https://grafana.***/api"

Maybe issue because of deprecation? Or I missed something? Thank you

Hi there, Timur 👋

I gave it a test with a new slack app and fresh build, everything seems to be running fine for me. I have added some additional logging for you though, so we can figure this out. If you add to the top of your config.toml file log_level = "trace" then that will let you see more indepth messaging around the events being received. I also updated the error message to contain the user ID it is trying to query, just in case it is potentially not the ID we are expecting somehow.

Hopefully, a quick update fixed everything we needed to and your new build should work fine. If not then we can continue efforts to diagnose the pickle.

Cheers, Jack

Hello, yes, seems it's ok, I didn't test it in public channel. I tested it in private, so probably that's why. Now I see

And in the log:

time="2025-04-11T10:06:56Z" level=error msg="GetUserInfo error: user_not_found (You probably don't have the `users:read` scope)"
time="2025-04-11T10:07:01Z" level=trace msg="Received message `\"<@U08MBDW2CCC> has joined the channel\"`, not for us. ignoring"
time="2025-04-11T10:07:06Z" level=error msg="GetUserInfo error: user_not_found (You probably don't have the `users:read` scope)"
time="2025-04-11T10:07:07Z" level=error msg="GetUserInfo error: user_not_found (You probably don't have the `users:read` scope)"

But strange that I don't see in logs message "memo test message"
But why it doesn't work in private channel? is it expected?
