Ive noticed that my bot keeps going offline on slack and so when a user tries to message it, it does not give any output back, when checking Bluemix, which is where I have deployed the bot, the app is still reported as online and there are no logs reporting any issues, the only way I have found to resolve this is to restart the bot on Bluemix, this then makes it active on Slack again and allows a user to message it, but then after a while the same thing will happen again.

It seems that the WebSocket connection does not like it when too many messages are sent at the same time and can result in the following error:

java.lang.IllegalStateException: The remote endpoint was in state [TEXT_PARTIAL_WRITING] which is an invalid state for called method

This never resolves itself and requires a full reboot of the service to make it work again. This appears to be partially due to the fact that the ping service running in the background might occasionally conflict with the user called reply function and this concurrency causes an unresolvable exception within the websocket session.

Most suggestions seem to suggest that wrapping the sendMessage within a synchronized block can fix this issue so the Bot class would need to be restructured slightly to support this.

Has anyone else run into this issue or have any suggestions?

After deploying to Heroku and attempting to run the app I am seeing this error message in the logs: Error: Unable to access jarfile jbot-example/target/jbot-example-1.0.0-SNAPSHOT.jar

I have checked this is the correct name for the jar file and this is the jar file that is auto-created when running mvn spring-boot:run.

My procfile looks like this: web: java -Dserver.port=8080 -jar jbot-example/target/jbot-example-1.0.0-SNAPSHOT.jar

And the path from the jbot directory to the jar file is jbot-example\target\jbot-example-1.0.0-SNAPSHOT.jar

Any help with this would be greatly appreciated

This is the first time I've used Heroku so not sure if I am missing anything.

This PR attempts to solve multi-threaded access to the WebSocketSession causing TEXT_PARTIAL_WRITING errors as detailed in this ticket along with allowing the Ping task to be reset.

The multi-thread lock to sendMessage should remove partial write errors but I am still a bit confused about how to actually reset the whole system in case the socket session becomes unrecoverable.

Is it just about calling startRTMAndWebSocketConnection again if I can detect that the service is struggling? Does the "manager" then need to be stored so it can be stopped and started cleanly in this case?

I've been trying to run jbot-example–I cloned the repository, ran mvn install in the jbot folder, went into jbot-example and ran mvn spring-boot:run, but it throws this error:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.4.0.RELEASE:run (default-cli) on project jbot-example: An exception occurred while running. 
null: InvocationTargetException: Error creating bean with name 'slackBot': Invocation of init method failed; 
nested exception is java.lang.NoClassDefFoundError: org/apache/tomcat/util/res/StringManager: org.apache.tomcat.util.res.StringManager -> [Help 1]

It seems to be totally random - after a few hours or days the bot will just crash. I'm running a barely modified version of the example bot on a dedicated Ubuntu 16 server doing nothing else. There isn't much to go on in the logs. Is there a place to catch this exception and reestablish the connection?

EDIT: Seems to be the same as #97

Using 3.0.3-SNAPSHOT as I want the reply feature of messages, but get the following error when the bot responds:

hi, Slack bot is continuously toggles (going on and off) with below error since yesterday. It tries to ping and comes up for some time and then after couple of times it goes down permanently ( never comes up until i deploy the app again) . Could you please look into this websocket issue

Hi, I have encountered a big issue. Say you entered a slack domain and it has several users. When a new user that haven't yet talked to the JBot, the JBot fails to take inputs. But when a restart of the spring-boot service is done, those users who tried interacting with the bots and failed are now are able to interact. Can you please, tell me where can the problem be as soon as possible. :)

Hi,

I think I spotted a bug. If we take you meeting scheduler example, even if you stop the conversation by answering "no" to the askWhetherToRepeat step, then, forever, all the steps are called. So the conversation is not really closed.

I hope that's clear...

Hii everyone, i'm trying to send file to slack using Jbot, i saw an issue that use the Meteoroid library to do it, but when i get the maven dependecy of the library it doesn't work for me, if there some suggestion please ?

Internally we have been using this bot for some years successfully but given the number of CVE's present in the current version of springboot we have ended up forking the library and bumping dependencies there.

We have successfully upgraded it to v2.7.6 with Java 11 and would be happy to contribute this back if that is of interest!

Hi, I wanted to create my custom slack bot by extending ur Bot class. But, how can I run my bot in a standalone application (the bot should run continuously in the background) without using spring boot? Any guidance on this pls?

Currently the bot with either Facebook or Slack will accept any string for time and schedule it.

User story: user: setup meeting bot: At what time (ex. 15:30) do you want me to set up the meeting? user: no bot: you meeting is set at no. Would you like to repeat it tomorrow?

Some sort of time validation should be implemented to avoid this bug.

I get this error [1] - I think it might be tied to using a deprecated method which is warned about in the response, but there is an error unmarshalling the unknown field?
