Error message

You do not have permission to delete this queue item

What it means

HTTPException(403) raised in DELETE /session_queue/{queue_id}/i/{item_id} when the authenticated user is neither the owner of the queue item chain's root item nor an admin. Authorization is deliberately based on the root owner because the delete removes the entire workflow-call chain.

Solutions

1. Have an admin perform the delete, or log in as the user who owns the root queue item
2. If the token should own the items, re-enqueue using the intended user's credentials
3. Ask the server admin to grant admin rights if this account legitimately needs to manage all queue items

Example fix

// before: delete as wrong user -> 403
await api.delete(`/api/v1/session_queue/${queueId}/i/${itemId}`)
// after: check ownership client-side first
if (rootItem.user_id !== currentUser.id && !currentUser.is_admin) {
  throw new Error('Not permitted; ask an admin or the owner')
}

// check ownership before attempting delete
const item = await api.get(`/api/v1/session_queue/${queueId}/i/${itemId}`)
if (item.data.user_id !== currentUser.id && !currentUser.is_admin) {
  throw new Error('Only the owner or an admin can delete this queue item')
}

function canDelete(item, currentUser) {
  return currentUser?.is_admin === true || item?.user_id === currentUser?.id
}

try {
  await api.delete(`/api/v1/session_queue/${queueId}/i/${itemId}`)
} catch (e) {
  if (e.response?.status === 403) {
    notify('You lack permission to delete this item; ask an admin or the owner')
  } else throw e
}

When it happens

Trigger: A non-admin user calling DELETE on a queue item whose root_queue_item.user_id differs from their own user_id — e.g. deleting another user's queued generation in a shared/multi-user InvokeAI deployment.

Common situations: Multi-user setups where users share queue visibility but not delete rights; service accounts or API tokens running as a different user than the one who enqueued the item; sessions switching users while a UI keeps old items loaded.
