And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### Small Errors Automatically Handled

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

Da `needy` ein erforderlicher Parameter ist, müssen Sie ihn in der URL setzen:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

import (
	"context"
	"sync"
	"sync/atomic"
	"time"
)

// Opts contains options for the cache.
type Opts struct {
	// When set to true, return the last cached value
	// even if updating the value errors out.
	// Returns the last good value AND the error.
	ReturnLastGood bool

	// If NoWait is set, Get() will return the last good value,
	// if TTL has expired but 2x TTL has not yet passed,

			}
			want += int64(len(tmp) - len(after))

			return buf[:want], err

		default:
			return nil, errors.New("unknown minor metadata version")
		}
	default:
		return nil, errors.New("unknown major metadata version")
	}
}

func decodeXLHeaders(buf []byte) (versions int, headerV, metaV uint8, b []byte, err error) {

```

Uma alternativa que você pode utilizar para capturar exceções (e possivelmente lançar outra HTTPException) é criar um [Manipulador de Exceções Customizado](../handling-errors.md#instalando-manipuladores-de-excecoes-customizados){.internal-link target=_blank}.
