Scriptrunner script works in console but not in a listener

[Kevin Bouman]

I am trying to create a Slack channel when a version is created. I created a script that that can create a slack channel from Jira. It works when executing it in the script console but not when I put it into a listener. The frustrating thing is that I am getting a 200 response in the listener logs. Nothing is changed between the console and listener scripts. The Slack bot is also that same. I am on Jira Datacenter.

What am I missing?

Script

import groovyx.net.http.ContentType

import groovyx.net.http.RESTClient

import groovyx.net.http.HttpResponseDecorator

import groovyx.net.http.RESTClient

final String URL = "https://slack.com/api/"

def channelName = "pretend-channel-4"

def channelPrivacy = "false" //true = private / false = public

def data = [:]

 

data.put("name", channelName)

data.put("is_private", channelPrivacy)

data.put("prety", "1")

def postResponse = post(URL, "conversations.create?", data)

def post(def hostUrl, def endpointAndQuery, def bodyJson) {

    //TOKEN FOR SLACK APP

    def SLACK_API_TOKEN = "<SLACK TOKEN>"

    def client = new RESTClient(hostUrl)

    client.setHeaders([

        'Authorization': "Bearer $SLACK_API_TOKEN"

    ])

    client.handler.success = { HttpResponseDecorator response ->

        log.debug("POST Success: $response.")

    }

    client.handler.failure= { HttpResponseDecorator response ->

        log.error "POST Error: $response.status"

    }

    client.post(

            path: endpointAndQuery,

            contentType: ContentType.JSON,

            body: bodyJson

    )   

}

Thanks @PD Sheehan for your support.

Turns out that my script was correct. The problem was the channel name I was using. Slack has specific requirements for naming a channel. I was creating my name based off the version description. Because of this, I have to parse out all special characters, spaces and capitals. I also had to limit the string length to 80 characters.

Here is my updated code

import org.apache.log4j.Level
//For Slack POST
import groovyx.net.http.ContentType
import groovyx.net.http.RESTClient
import groovyx.net.http.HttpResponseDecorator
import java.util.*
import java.io.*

/////////////// GET EVENT DETAILS /////////////////
def fieldMap = [:]
fieldMap["versionName"] = event.getVersion().getName()
fieldMap["versionReleaseDate"] = event.getVersion().getReleaseDate()
fieldMap["parsedReleaseDate"] = event.getVersion().getReleaseDate().toString().substring(0,10)
fieldMap["versionStartDate"] = event.getVersion().getStartDate()
fieldMap["versionDescription"] = event.getVersion().getDescription()

/////////////// CREATE SLACK CHANNEL /////////////////
def slackchannelName = fieldMap.versionDescription.toString()
def slackchannelPrivacy = "false" //true = private / false = public
def slackchannelNameModified = slackchannelName.toLowerCase().replaceAll("[^a-zA-Z0-9]","-")
def slackchannelNameModified2 = slackchannelNameModified.replaceAll("\\s+","-")

log.debug("slackchannelNameModified: " + slackchannelNameModified.length() + " = $slackchannelNameModified")

Vector<Character> v = new Vector<>();

for (int i = 0; i < slackchannelNameModified.length(); ++i){
    def myChar = slackchannelNameModified.charAt(i)
    v.add(myChar);
    if (v.size() > 1 && myChar == "-"){
        int sz = v.size();
        // removing two consecutive duplicates
        if (v.get(sz - 1) == v.get(sz - 2)){
            v.setSize(sz - 2); // Removing two characters from the string
        }
    }
}

//Puting the string back together
def endChannelName = ""

for(n in v){
    endChannelName = endChannelName + n
}

//endChannelName.take(80)
log.debug("endChannelName: " + endChannelName.length() + " = $endChannelName")

final String URL = "https://slack.com/api/"
def data = [:]
    data.put("name", endChannelName)
    data.put("is_private", "false") //slackchannelPrivacy)
    data.put("prety", "1")
def postResponse = post(URL, "conversations.create?", data)

def post(def hostUrl, def endpointAndQuery, def bodyJson) {

    //TOKEN FOR SLACK APP
    def SLACK_API_TOKEN = ""
    def client = new RESTClient(hostUrl)
    client.encoder.charset = 'utf-8'
    client.setHeaders([
            'Authorization': "Bearer $SLACK_API_TOKEN"
    ])

    client.handler.success = { HttpResponseDecorator response ->
        log.debug("POST Status: $response.")
        log.debug("POST Response: $response.entity.content.text")
    }

    client.handler.failure = { HttpResponseDecorator response ->
        log.error "POST Error: $response."
    }

    client.post(
            path: endpointAndQuery,
            contentType: ContentType.JSON,
            body: bodyJson
    )
}

So, when executing in the listener, you get a log entry that shows the post request was successful but the corresponding slack channel isn't created?

It's possible for an API to respond with a success status code, but report a failure as part of the message.

Maybe you need to extract a bit more out of that response to get some clues. 

import groovyx.net.http.ContentType
import groovyx.net.http.HttpResponseDecorator
import groovyx.net.http.RESTClient

final String URL = "https://slack.com/api/"
def channelName = "pretend-channel-4"
def channelPrivacy = "false" //true = private / false = public

def data = [:]
data.put("name", channelName)
data.put("is_private", channelPrivacy)
data.put("prety", "1")

def postResponse = post(URL, "conversations.create?", data)

def post(def hostUrl, def endpointAndQuery, def bodyJson) {
    //TOKEN FOR SLACK APP
    def SLACK_API_TOKEN = "<SLACK TOKEN>"

    def client = new RESTClient(hostUrl)
    client.setHeaders([
            'Authorization': "Bearer $SLACK_API_TOKEN"
    ])

    client.handler.success = { HttpResponseDecorator response ->
        log.debug("POST Status: $response.")
        log.debug("POST Response: $response.entity.content.text")
    }

    client.handler.failure = { HttpResponseDecorator response ->
        log.error "POST Error: $response."
    }

    client.post(
            path: endpointAndQuery,
            contentType: ContentType.JSON,
            body: bodyJson
    )

}

@PD Sheehan Thanks for the direction. It looks like it is doing exactly what you say. The request is successful but I am getting 

POST Response: {"ok":false,"error":"invalid_name_specials","warning":"missing_charset","response_metadata":{"warnings":["missing_charset"]}}

do you know how to fix this? I have never had to define the ContentType other then what is currently in the script. From what I can tell it needs the Charset defined. 

[PD Sheehan]

I don't think it'a content type error.

I haven't worked with Slack API before, but a quick google search revealed this:

https://api.slack.com/methods/conversations.create#errors

See the "invalid_name_specials" error.
That means your channel name "pretend-channel-4" is apparently invalid.

[PD Sheehan]

And if you want to take care of the warning too... you can try adding something like this:

client.encoder.charset = 'utf-8'

But I'm not sure. I've never tried that. I just found it from the javadocs.
