# E1748 — CIP-34: auction already open for this request

| Property | Value |
| - | - |
| **Code** | `1748` |
| **Slug** | `E1748` |
| **Category** | `commit_reveal` (Commit-Reveal) |
| **CIP** | CIP-34 §Sealed-Bid |

## What happened

Cip34: auction already open for this request.

This is the receipt's `what` text, produced by the node's `ExecutionError::AuctionAlreadyOpen`.

## Why it happened

The node rejected the operation with `E1748` (category `commit_reveal`, Commit-Reveal). The receipt's `why` field carries the specific cause and `context` carries structured details, when the emitter attaches any.

The normative rule is in CIP-34 §Sealed-Bid.

## How to fix

An auction for this request\_id is already open — one auction is allowed per request\_id; wait for it to reveal or grace-cancel first.

## Receipt example

```json theme={null}
{
  "code": 1748,
  "slug": "E1748",
  "category": "commit_reveal",
  "what": "cip34: auction already open for this request",
  "fix": "An auction for this request_id is already open — one auction is allowed per request_id; wait for it to reveal or grace-cancel first.",
  "docs_url": "https://docs.cowboy.inc/errors/E1748"
