# 404 Not Found Caused by an Incorrect Request URL

This article examines an error that might occur when you send a request to YouTrack REST API. You can face this error when the request URL contains an unsupported path or an encoded whitespace character.

## Error Message

```JSON
{
    "error": "Not Found",
    "error_description": "HTTP 404 Not Found"
}
```

## Request Details

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

| Attribute | Value |
| --- | --- |
| Request method | POST |
| Incorrect endpoint | `/api/admin/issues%C2%A0` |
| HTTP response code | 404 |

This endpoint in this example is incorrect and caused the error. The `%C2%A0` sequence is an encoded non-breaking space appended to the path.

## Troubleshooting

Here are some possible causes and suggestions on how to overcome the error and send the request to the correct resource.

### Cause

The request URL is incorrect. In this example, the path contains the unsupported `/api/admin/issues` resource and ends with `%C2%A0`, which is an encoded non-breaking space.

### Solution

Check the request URL against the REST API reference and remove encoded whitespace characters from the path.

To create an issue, send the request to the following endpoint:

```
/api/issues
```
