VNTANA List Workspaces

This is the simplest node in the pack and also one of the most useful to run first. VNTANAListWorkspaces takes only your credentials and returns two parallel lists: workspace_uuids and workspace_names - every workspace your VNTANA account belongs to.

Why you'll actually use it

Two reasons, and they're both "before anything else" chores.

First, it's the recommended connection test. The Credentials node validates your login by listing workspaces internally, so if you wire Credentials → ListWorkspaces and get a clean list back, your whole auth setup is confirmed working. You can stop guessing whether the email, password, and org UUID are right and just look at the output.

Second, it's how you find valid workspace UUIDs. Every download, upload, and search node needs a workspace, and the default_workspace_uuid you set on Credentials has to be a real one. Run this node, read the list, copy the UUID you want, and paste it into your Credentials node. The names make it painless - you'll see the actual workspace names, not just a wall of UUIDs, and the lists line up by position.

The honest shape of it

It's a two-output read-only node: workspace_uuids and workspace_names, both STRING lists. Nothing else - no filters, no search, no workspace override (it lists across your whole org). It costs one API call per run, which is nothing.

Install

Same pack as everything here - a thin REST client, no model downloads:

cd ComfyUI/custom_nodes
git clone https://github.com/VNTANA-3D/vntana-comfyui-node
cd vntana-comfyui-node
pip install -e .

Restart ComfyUI. Or use ComfyUI Manager and search "vntana-comfyui-node".

Troubleshooting

• Empty list - you can see some workspaces; if this returns nothing, either the account genuinely has no workspaces assigned, or auth succeeded but the org is scoped somewhere unexpected. Check the dashboard.
• Auth error on the Credentials node - that's the front door failing, not this node. Fix email/password/org UUID first.

That's the whole node. Unsexy, but it's the difference between copying workspace UUIDs out of a dashboard you don't remember how to navigate and getting them right there in your graph.
