# Data - Troubleshooting

### Path too long

If you get an error "Unable to generate credentials from the objectstore as the requested path is too long." from AWS when requesting temporary credentials, then the path should be shortened.

You can truncate the sample name and user reference or use advanced output mapping in the API which avoids generating the long folders and creates output in the targetPath-defined location.

```
"analysisOutput": [
{
"sourcePath": "out",
"type": "FOLDER",
"targetProjectId": "enter_your_target_project_id",
"targetPath": "/enter_your_target_folder/"
}
]
```

### Files remaining on own S3 Storage

Before copy and move operations are executed **on your own S3 storage**, a test is performed to verify the necessary operational rights. If an issue is encountered, the copy/move action is aborted and the test files can be left behind due to missing rights. These files can safely be manually deleted from your S3 console.
