Because it's a Python exception, you don't `return` it, you `raise` it.

And will also be used in the API docs inside each *path operation* that needs them:

## Editor support { #editor-support }

In your editor, inside your function you will get type hints and completion everywhere (this wouldn't happen if you received a `dict` instead of a Pydantic model):

      description='Extracts ResultStore links from a build log.\n'
                  'These can be then printed out, and/or output into a '
                  'JUnit-based XML file inside a specified directory.')

  parser.add_argument('build_log',
                      help='Path to a build log.')

### More technical details { #more-technical-details }

You might have noticed that `await` can only be used inside of functions defined with `async def`.

But at the same time, functions defined with `async def` have to be "awaited". So, functions with `async def` can only be called inside of functions defined with `async def` too.

So, about the egg and the chicken, how do you call the first `async` function?

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package cmd

import (
	"syscall"
)

// Returns true if no error and there is no object or prefix inside this directory
func isDirEmpty(dirname string, legacy bool) bool {
	if legacy {
		// On filesystems such as btrfs, nfs this is not true, so fallback
		// to performing readdir() instead.
		entries, err := readDirN(dirname, 1)

#!/usr/bin/env bash
# This script will run inside ubuntu-pod that is located at default namespace in the cluster
# This script will not and should not be executed in the self hosted runner

echo "script failed" >resiliency-initial.log # assume initial state

echo "sleep to wait for MinIO Server to be ready prior mc commands"
# https://github.com/minio/mc/issues/3599

MINIO_SERVER_URL="http://127.0.0.1:9000"
ALIAS_NAME=myminio
BUCKET="test-bucket"

The contents that you return from your *path operation function* will be put inside of that `Response`.

	// Iterating over the cases, fetching the object validating the response.
	for i, testCase := range testCases {
		// initialize HTTP NewRecorder, this records any mutations to response writer inside the handler.
		rec := httptest.NewRecorder()
		// construct HTTP request for Get Object end point.
		req, err := newTestSignedRequestV4(http.MethodHead, getHeadObjectURL("", testCase.bucketName, testCase.objectName),

`xl.meta` carries three types of object entries which designate the type of version object stored.
