Delete Version In GenAsset

Versioning systems have a dirty little secret: the delete button is more dangerous than the commit button. Delete Version In GenAsset is that button, and the pack is fully aware - that's why this node has a second safety on it. Give it a version_id and it will happily call DELETE on the version, but only if you've also flipped confirm_delete to true. No confirm, no delete.

That two-switch design isn't bureaucracy, it's damage control. A version is someone's approved output, the parent of a branch, or the one reference everyone's agent workflows load. Deleting one by accident in a shared workspace is a "whoops" that takes real effort to undo, so the pack makes the destructive act impossible to do by accident - you have to intend it twice.

How it works

The node does a DELETE request to api/v1/versions/{version_id} with your workspace token. Before it bothers the server, it checks two things: that version_id isn't empty, and that confirm_delete is actually true. Fail either check and you get an error in status_json telling you exactly what's missing - "Set confirm_delete=true to delete a version."

That's the entire mechanism. There's no undo, no trash can mentioned anywhere in the pack's docs, so treat the delete as permanent for the asset's history. Note that this deletes a version, not the whole asset - the asset and its other versions stay put.

Inputs and outputs that matter

Three required inputs: base_url, token, version_id, and the boolean confirm_delete. The version id is the only real work - grab it from a save node's output, List Asset Versions In GenAsset, or the web UI, and double-check it before you commit. confirm_delete defaults to false, which is the entire point: the node ships in "safe" mode and only deletes when you explicitly flip it.

Outputs are minimal: version_id (echoes back what you deleted) and status_json with the server's result. Both are mostly for confirmation.

Installation

Part of the steliosot/ComfyUI-GenAsset pack. ComfyUI Manager → search GenAsset → install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/steliosot/ComfyUI-GenAsset.git

Restart after installing. No extra pip dependencies; just a workspace token (widget, GENASSET_WORKSPACE_TOKEN, or ComfyUI/user/genasset.json).

Common issues

• "Set confirm_delete=true to delete a version." - you forgot the second switch, or you're testing in a workflow that resets the boolean each run. That's the safety working as intended.
• "Paste version_id." - empty input; the node won't guess.
• A version you want is gone - before you deleted, did you check whether it's a branch parent or the promoted current version? The pack doesn't block deleting a promoted version, so if you delete the current one, the asset's current_version_id points at a deleted version until you promote another. Worth checking Promote Version In GenAsset after a cleanup session.

The rule of thumb: keep confirm_delete wired to a toggle you consciously flip, not a constant true buried in a saved workflow. Deleting is forever, and the pack's authors clearly believe you should feel the click.
