Workspace does not exist.

Error message

Workspace does not exist.

What it means

Existence guard in validWorkspaceSlug middleware: no workspace matches the URL slug (in multi-user mode, scoped to the requesting user), so the route param is invalid and a 404 is returned before the handler runs.

Solutions

1. Check the workspace slug in the URL — it must exactly match an existing workspace slug.
2. In multi-user mode, verify the requesting user has access to that workspace.
3. Create the workspace first if it does not exist.

When it happens

Trigger: Request referenced a workspace that does not exist. Triggered when validWorkspace middleware cannot find the workspace by slug/id (validWorkspace.js:14).

Common situations: See trigger scenarios.
