Error when adding slack to Jira Helpdesk

Hi @IT Helpdesk 

Welcome to the community.

Have you tried these steps to permit and integrate your Slack workspace?

To set up chat in your service project:

1. From your service project sidebar, select Channels, then Chat, then Configure.

2. Select Add to Slack.

3. Select the Slack workspace you want to connect your Jira site to then select Allow.

Tip: If another service project on your Jira site is connected to Slack, you can’t select another workspace.

4. Select the request types you want to use in Slack, then select Add. You can add more later.

5. The last step creates a private agent channel for your team. Assist suggests a name based off your project key, but you can rename it if you want.

6. Select Create to finish setup.
