| Fields ||
|---|---|
| `totalObjectCount` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of objects listed. |
| `succeededObjectCount` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of objects completed. |
| `failedObjectCount` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. The number of objects that failed due to user errors or service errors. |
| `totalBytesFound` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of bytes found from source. This field is only populated for jobs with a prefix list object configuration. |
| `objectCustomContextsCreated` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of object custom contexts created. This field is only populated for jobs with the UpdateObjectCustomContext transformation. |
| `objectCustomContextsDeleted` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of object custom contexts deleted. This field is only populated for jobs with the UpdateObjectCustomContext transformation. |
| `objectCustomContextsUpdated` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. Number of object custom contexts updated. This counter tracks custom contexts where the key already existed, but the payload was modified. This field is only populated for jobs with the UpdateObjectCustomContext transformation. |
| `totalBytesTransformed` | `string (https://developers.google.com/discovery/v1/type-format format)` Output only. The total number of bytes affected by the transformation. For example, this counts bytes deleted for `DeleteObject` operations and bytes rewritten for `RewriteObject` operations. |
