slackUserIdFromEmail() Doesn't Work

[pporee]

Version report

Jenkins 2.277.3 Slack Notification Plugin 2.48

Issue

Hi,

I got the same issue reported here https://github.com/jenkinsci/slack-plugin/issues/763, the func return null and no errors or debug informations are available.

Scopes

Here the scopes for my slack app. chat:write files:write users:read users:read.email

Token

Config as Code

slackNotifier:
    botUser: true
    room: "xxx-notifications"
    sendAs: "Jenkins"
    sendAsText: false
    slackUserIdResolver: "email"
    teamDomain: "xxx"
    tokenCredentialId: "slack-token"

thanks for your help. Below my code:

script {
  def lastCommiterEmail = sh(returnStdout: true, script: 'git log --format="%ae" | head -1').trim()
  def slackUserId = slackUserIdFromEmail("${lastCommiterEmail}")
  slackSend(botUser: true, tokenCredentialId: 'slack-token', color: "good", message: "<@${slackUserId} test message")
}

Result:

Reproduction steps

I tested directly with my slack email in the slackUserIdFromEmail function but got the same result.

Please provide more information, i.e. scopes, what resolution strategy you have configured in your global config?

[pporee]

@timja Added scopes, creds and my config as code, if you need more tell me :). Regards

[timja]

the resolution strategy for slack IDs? it's in the advanced settings on the global configuration

[pporee]

As my app is part of my organisation i only found that parameter under my app scope. Is it what you need or do i need to ask to slack administrators ?

[timja]

No in your jenkins configuration, system configuration page

[pporee]

sorry i can't find more informations, i gave you all i got :(

Talked to Slack about the same problem. They have changed the way their REST API receives the OAuth token. Because of that the plugin does not work with getting the emails.

https://api.slack.com/changelog/2020-11-no-more-tokens-in-querystrings-for-newly-created-apps

I do not know to program in java but if someone that can , would change the way the OAuth token is sent to Slack then it would work @timja

We use the header not the query string: https://github.com/jenkinsci/slack-plugin/blob/955756034a9addb3fbbed7b741c564a36b112a4b/src/main/java/jenkins/plugins/slack/user/EmailSlackUserIdResolver.java#L137

A couple of things you could try:

• Go to Manage Jenkins > Configure System > Look for the Slack section > Advanced... > In User ID Resolver check Slack email User ID Resolver
• There is already a function that finds the user IDs of the committers, that is

  def userIds = slackUserIdsFromCommitters()
  def userIdsString = userIds.collect { "<@$it>" }.join(' ')

  it is also documented here.

Finally, FYI, you can limit the number of git commits shown by git log like this:

git log -1 --format="%ae"

No need to bother the head command👍

Faced the same issue today. Do you have any updates on it?

+1 Experiencing the same issue.

My app has the required permissions and the Email User resolver option is enabled on Jenkins.

I found the same issue. My issue was that when I printed out the git committer it was a jenkins user. When I added

options {
  skipDefaultCheckout()
}
stages {
  stage('Checkout') {
    steps { checkout scm }
  }
}

then I had a real committer.

We ran into this same issue. We're not able to resolve Slack userIds from email.

• Jenkins --> 2.303.1 version
• Slack Notification --> 2.48 version
• The Slack email User ID Resolver is checked
• The email I'm using with git operations is the one correctly associated with my Slack user
• The custom bot we're using has the right and required permissions, users:read and users:read.email

I've tried with a simple snippet like this one

def sendSlackNotification() {
  // test with 'slackUserIdFromEmail'
  def lastCommitterEmail = sh(returnStdout: true, script: 'git log --format="%ae" | head -1').trim()
  echo "commit author ${lastCommitterEmail}"
  def slackUserId = slackUserIdFromEmail("${lastCommitterEmail}")
  slackSend(color: "good", message: "@${slackUserId} 'slackUserIdFromEmail' message", channel: channel)

  // test with 'slackUserIdsFromCommitters'
  def userIds = slackUserIdsFromCommitters()
  def userIdsString = userIds.collect { "<@$it>" }.join(' ')
  slackSend(color: colorCode, message: "${userIdsString} 'slackUserIdsFromCommitters' message", channel: channel)
}

but I get nothing, see image below.

If I use the Slack userId directly it does work i.e.

def sendSlackNotification() {
  // test with userId
  def userId = "@{my-slack-user-id}"
  slackSend(color: colorCode, message: "${userId} 'userId' message", channel: channel)
}

then it does work. Any hint? In master node's /var/log/jenkins/jenkins.log file I can only see this warning, nothing more useful

We experience similar issue as posted above with the more recent versions as well:

• Jenkins 2.440.2
• Slack notification plugin 684.v833089650554

Enabled additional logging as described here but in the resulting log there are no details about the api calls being made by slack plugin to slack and their results. It only posts log messages like the one below:

Apr 23, 2024 3:39:20 PM FINE jenkins.plugins.slack.StandardSlackService
Posting succeeded

Any guidance on how to troubleshoot it further?
