        {

```

## Request Details

Here are the details about a sample request that might result in this error.

| Attribute | Value |
| --- | --- |
| Request method | POST |
| Endpoint | `/api/admin/projects?template=PT` |
| Request body |     ```JSON {     "description": "test",     "name": "369 Moser Krebs Uetendorf",     "shortName": "369",     "leader": {         "id": "1-1"     } } ```    |
| HTTP response code | 400 |

## Troubleshooting

Here are some possible causes and suggestions on how to overcome the error and create the project.

### Cause

The value passed in the `shortName` attribute is used as the project ID. Project IDs cannot contain only digits.

### Solution

Replace the numeric value in the `shortName` attribute with a non-numeric project ID.

For example, use `MOKU369` or another value that contains at least one letter:

```JSON
{
    "description": "test",
    "name": "369 Moser Krebs Uetendorf",
    "shortName": "MOKU369",
    "leader": {
        "id": "1-1"
    }
}
```
