Description

Creating a workspace via the CLI fails when the JetBrains module is present. During the parameter prompting step, the CLI hangs with an empty prompt (i.e., no input description, no available options). The only way to proceed is by pressing Ctrl-C, after which the CLI continue and ends up failing with an error due to an empty value for the jetbrains_ides parameter.

This leads to a broken workspace creation experience.

Current Behaviour

Steps shown in the video:

1. With JetBrains module (active template version c9ed0dd)

• Tested on our dogfood environment using "Write Coder on Coder" template with the active version (c9ed0dd) that includes the JetBrains module.
• After filling other required parameters, the CLI shows a blank prompt for jetbrains_ides.
• No instructions or options are presented.
• Exiting the prompt via Ctrl-C, the create process continues.
• Failure due to empty value for jetbrains_ides parameter.

Error message:

2025-08-04 10:44:52.463Z
2025-08-04 10:44:52.464Z value "" is not a valid list of strings

2. Without JetBrains module (strange_fermi7 template version):

• Same setup, but using a template version that does not include the JetBrains module (strange_fermi7)
• Only the required parameters are prompted.
• The workspace is created successfully without issues.

Expected Behaviour

The CLI should:

• Prompt users properly with a clear description and list of valid JetBrains IDEs (if applicable).
• Allow skipping the parameter (i.e., selecting "none").
• Accept the JetBrains IDE value via --parameter flag. (edit: ✅ working correctly as shown in Bug: CLI Workspace Creation Fails When JetBrains Module Is Present #19145 (comment))
• Execute workspace creation successfully in both interactive and non-interactive modes.

Additional Context

• Environment: Dogfood
• Template: Write Coder on Coder (coder)
• Versions tested:
  • ❌ Currently active template version (c9ed0dd) with JetBrains module (broken)
  • ✅ strange_fermi7 without JetBrains module (works)
