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

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

... Das funktioniert:

                @Throws(Exception::class)
                override fun doExecute(inputStream: ZipInputStream) {
                    var zipEntry = inputStream.nextEntry
                    while (zipEntry != null) {
                        processEntry(zipEntry, builder)
                        zipEntry = inputStream.nextEntry
                    }
                }
            })
        }
