You could use it while developing your app to log the body and debug it, return it to the user, etc.

```Python hl_lines="14"
{!../../docs_src/handling_errors/tutorial005.py!}
```

Now try sending an invalid item like:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

You will receive a response telling you that the data is invalid containing the received body:

     * `ID <= lastGoodStreamId` can only be replayed on a new connection if they are idempotent.
     *
     * @param lastGoodStreamId the last stream ID the peer processed before sending this message. If
     *     [lastGoodStreamId] is zero, the peer processed no frames.
     * @param errorCode reason for closing the connection.
     * @param debugData only valid for HTTP/2; opaque debug data to send.

// by AWS S3.
//
// An AWS S3 ETag is 16 bytes long and, in case of a multipart
// upload, has a `-N` suffix encoding the number of object parts.
// An ETag is not AWS S3 compatible when encrypted. When sending
// an ETag back to an S3 client it has to be formatted to be
// AWS S3 compatible.
//
// Therefore, Format returns the last 16 bytes of an encrypted
// ETag.

	if !skipAccessChecks(opts.Bucket) {
		// Stat a volume entry.
		if err = Access(volumeDir); err != nil {
			return convertAccessError(err, errVolumeAccessDenied)
		}
	}

	// Use a small block size to start sending quickly
	w := newMetacacheWriter(wr, 16<<10)
	w.reuseBlocks = true // We are not sharing results, so reuse buffers.
	defer w.Close()
	out, err := w.stream()
	if err != nil {
		return err
	}

2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).

            return;
        }
        Smb2NegotiateRequest negoReq = new Smb2NegotiateRequest(sess.getConfig(), trans.getRequestSecurityMode(nego));

        log.debug("Sending VALIDATE_NEGOTIATE_INFO");
        Smb2IoctlRequest req = new Smb2IoctlRequest(sess.getConfig(), Smb2IoctlRequest.FSCTL_VALIDATE_NEGOTIATE_INFO);
        req.setFlags(Smb2IoctlRequest.SMB2_O_IOCTL_IS_FSCTL);

		}
	}

// SafeClose safely closes any channel of any type
func SafeClose[T any](c chan<- T) {
	if c != nil {
		close(c)
		return
	}
	// Print stack to check who is sending `c` as `nil`
	// without crashing the server.
	debug.PrintStack()

	if len(systemTgts) == 0 {
		return
	}

	// Iterate over all logger targets to send the log entry
	for _, t := range systemTgts {
		if err := t.Send(ctx, entry); err != nil {
			if consoleTgt != nil { // Sending to the console never fails
				consoleTgt.Send(ctx, errToEntry(ctx, "logging", fmt.Errorf("unable to send log event to Logger target (%s): %v", t.String(), err), entry.Level))
			}
		}
	}
