Slackbot does not function and I see that No web socket url returned by Slack

[techiechat]

I newly created the slackbot token and git cloned the code
then I added the slackbot token in application properties file.
and made few changes in controller and service code

then started the slack bot app and even though slack app is started it doesnot function as intended.
below is the error I see in the console :

2020-09-28 23:53:07.507 ERROR 12828 --- [ main] me.ramswaroop.jbot.core.slack.Bot : No web socket url returned by Slack.

Can you please help me debug this ?

"No web socket url returned by Slack. " is the returned in console
It seems like its unable to startRTM And WebSocketConnection ...

I have created slackbot app and added slack token in application.properties
Am i missing something here?

No, that should be it. Just paste the token in application.properties file and make sure you have slack in active profiles like below:

# jbot
spring.profiles.active=slack
spring.jackson.property-naming-strategy=SNAKE_CASE
logging.level.me.ramswaroop=DEBUG
server.port=8080

# slack integrations
slackApi=https://slack.com/api
slackBotToken=<paste your slack bot token>             # <-------------- your token here

I run into the same Issue, cloned, didn't make any changes except copying the bot token to the application.properties and removing the facebook profile (only slack is active).

The App seems running and in the Log there is one Error No web socket url returned by Slack.

The Bot doesn't seem to react to any messages (or anything as far as I can tell). The Bot token scopes are channels:history, channels:join, chat:write, im:read, im:write, reactions:read, reactions:write.

What I expected to happen is that I run the sample application and having the bot react to direct messages and to messages in the channel the bot is in that are in the form of "ab12ab" (as the javadoc on onReceiveMessage suggests). I don't see any activity in Slack or the log.
