```json theme={null}
{

  "title": "Validation failed",
  "status": 422,
  "code": "validation_failed",
  "errors": [{ "pointer": "/entries/0/region", "detail": "region is required" }]
}
```

The body parsed, but one or more fields are missing or out of range.

## What to do

Fix each field listed in `errors`, addressed by JSON Pointer into your request (for example `/entries/0/region`).
