RHEL8

Reproduction steps

Within a declarative pipeline (webhook URL edited below) I've added this

    stage('Notify sucess') {
        steps{
        discordSend(description: "${currentBuild.currentResult}: Job ${env.JOB_NAME} \nBuild: ${env.BUILD_NUMBER} \nMore info at: \n${env.BUILD_URL}", footer: 'No-Code', unstable: true, link: env.BUILD_URL, result: "${currentBuild.currentResult}", title: "${JOB_NAME} << CLICK", webhookURL: 'https://discord.com/api/webhooks/842304094/yeoAn6A_9XY2O71dFbhlt9lUZrAW6OnFEG7y')
            }
    }

Even if i use something far similar

discordSend description: '', footer: '', image: '', link: 'env.BUILD_URL', result: '', thumbnail: '', title: 'MoveFiles', webhookURL: 'https://discord.com/api/webhooks/842304094/yeoAn6A_9XY2O71dFbhlt9lUZrAW6OnFEG7y'

I don't think that's a bug. It sounds like you are missing something. If you are using a pipeline this works. Of course use your own webhook.

discordSend description: "Lua check for the win", footer: "This should be green, yellow means issues with the code, and red is just bad.", link: env.BUILD_URL, result: currentBuild.currentResult, title: JOB_NAME, webhookURL: 'https://discord.com/api/webhooks/YOURWEBHOOKHERE

I get the same issue as soon as I tick "Enable URL Linking"

Notifications are sent as expected when this is unchecked.

I have set the URL in the global Jenkins settings.

Having the same problem. Did find a fix?

[ojalmeida]

I was having the same problem, the solution for me was set the Jenkins URL

via UI:

Manage Jenkins > System > Jenkins Location > Jenkins URL

via JCasC (Helm instalation):

set .controller.jenkinsUrl in values file

I'm having the same issue:

Finished: SUCCESS

The URL is properly set in the global Jenkins settings:

(It's a direct Tailscale URL, so it doesn't have a TLD. The people in the Discord I'm sending this to, all have Tailscale set up, so clicking the link won't cause any issues for them.)

These are my plugin settings:

But if I disable URL linking, it works fine.
