Error tagging job version when trying to tag any job

[sforster-meteomatics]

Nomad version

1.9.7

Operating system and Environment details

Clients & Servers: Debian 12
User OS: Ubuntu 24.04
User Browser. Firefox 139.0.1

Issue

When trying to tag any job in the Nomad Web UI, it fails with an error pop up like

Error Tagging Job Version
job "nomad-debug-job" version 0 not found

On the server I see the same error, shown further below.

With the CLI , I can tag job versions without issue, as long as the -namespace parameter is provided. However, without the -namespace parameter, I get the same error. This leads me to believe that the Web UI does not correctly supply the namespace parameter when calling the Nomad API.

Reproduction steps

Try to tag any job version in the nomad Web UI.

Expected Result

The tag is created.

Actual Result

The above mentioned error occurs.

Nomad Server logs (if appropriate)

2025-07-02T07:36:18.194Z [ERROR] nomad.fsm: UpdateJobVersionTag failed: error="job "nomad-debug-job" version 0 not found"

Hi @sforster-meteomatics and thanks for raising this issue. I have been able to reproduce it locally using the following steps:

• Run a Nomad agent using nomad agent -dev
• Create a namespace via nomad namespace apply platform
• Run a job in the namespace
• Attempt to tag it via the UI

Looking at the agent logs and UI console, I believe you're analysis is correct that the UI does not correctly add the namespace query parameter to the request. I'll mark this issue for the backlog.
