## wiring.get_error_rows_key()


Return the default error-rows key of an asset.


Usage

``` python
wiring.get_error_rows_key(asset_key)
```


It takes no override, because an override is a `dg.AssetKey` to pass as it is.


## Parameters


`asset_key: dg.AssetKey`  
The key of the asset whose rows fail validation.


## Returns


`dg.AssetKey`  
`asset_key` with `__error_rows` added to its last part. The key prefix stays.


## Examples


``` python
import dagster as dg

import dagster_dataframely as dd

dd.wiring.get_error_rows_key(dg.AssetKey(["sales", "orders"]))
```


    AssetKey(['sales', 'orders__error_rows'])
