Slack Examples cannot receive events or messages

[martibi]

I have installed the express example app manually, and setup the bot scope accordingly, but I cannot receive any events or commands. There is a 500 Internal server error that is being returned.

I did not modify anything, I used the original version of the express example in botbuilder-slack:

1. Only the first call to events endpoint was successful:

2. Subsequently, when I tried to send a message to the app, 500 is returned:

3. My Slack app Events setup is as follows:

Slack commands also do not work, and are received correctly, but return with a 500 error:

@martibi Can you show the stacktrace of the error ? Only the 500 message will not help to troubleshoot the issue.

Thanks!

[martibi]

How do I print the stacktrace of the error?

[bilby91]

You should be able to do:

  bot.on("error", (error) => {
    console.log(error, error.stack)
  })

Adding bot.on("error") doesn't work, I had to modify the botbuilder-slack library code to display the error:

Anyway, this indicates that the bot was not installed successfully. installationUpdate is not being called, as there was no output from that function. Any ideas why?

@martibi : I am facing the same issue, have you able to figure out the reason?

[santiagodoldan]

@mohyt were you able to solve it?

[mohyt]

@santiagodoldan : I created a new connector as this one is using lots of deprecated versions

[santiagodoldan]

What do you mean by "lots of deprecated versions"? I could be wrong, but I think we have only 2 dependencies botbuilder and slack
