"AL: Publish full dependency tree for active project" throwing "UserNotAuthenticatedException" for OnPrem when no credentials are cached

[dannoe]

1. Describe the bug
I tried to publish the full dependency tree after my cached credentials expired. I tried to publish to a an on-prem docker container. It compiles the projects and then fails with the following error:

[2026-01-13 13:47:30.51] Error: Exception of type 'Microsoft.Dynamics.Nav.Deployment.Authentication.UserNotAuthenticatedException' was thrown.

[2026-01-13 13:47:30.51] Error: Failed to publish: MyApp

This does only affect on-prem. I could publish the full dependency tree for my cloud sandbox.

2. To Reproduce
Steps to reproduce the behavior:

• Clear credentials cache (or let it expire)
• Add an on-prem launch configuration to launch.json or to the workspace file
• Run the command "AL: Publish full dependency tree for active project"
• Open the "OUTPUT" view (Ctrl+Shift+U)
• Wait for the exception

3. Expected behavior
Asking for Username and Password and then publish the full dependency tree

4. Actual behavior
Not asking for username/password and throwing an error after compiling the projects.

5. Versions:

• AL Language: Version: 17.0.1998613
• Visual Studio Code: 1.108.0
• Business Central: BC25
• Operating System: Windows

** 6. Workaround **

• First use "AL: Publish with debugging" or any other Publish/Debug command except the full dependency thingy.
• Enter your credentials
• Run "AL: Publish full dependency tree ..."
