Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example { #a-dict-from-the-previous-example }

In the previous example, we were returning a `dict` from our dependency ("dependable"):

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

But then we get a `dict` in the parameter `commons` of the *path operation function*.

			return
		case <-t.C:
			m.lastHandout = time.Now()

			if m2, err := rpc.UpdateMetacacheListing(ctx, m); err == nil {
				if m2.status != scanStateStarted {
					if serverDebugLog {
						console.Debugln("returning", m.id, "due to scan state", m2.status, time.Now().Format(time.RFC3339))
					}
					return
				}
				m = m2
				if serverDebugLog {
					console.Debugln("refreshed", m.id, time.Now().Format(time.RFC3339))

				hr.After.Drives[i].State = madmin.DriveStateCorrupt
			}
		}
	}
	return hr, nil
}

// Populates default heal result item entries with possible values when we are returning prematurely.
// This is to ensure that in any circumstance we are not returning empty arrays with wrong values.

# Background Tasks { #background-tasks }

You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

	for rng, val := range values {
		m.Set(name, float64(val), append(labels, rangeL, rng)...)
	}
}

// MetricsLoaderFn - represents a function to load metrics from the
// metricsCache.
//
// Note that returning an error here will cause the Metrics handler to return a
// 500 Internal Server Error.
type MetricsLoaderFn func(context.Context, MetricValues, *metricsCache) error

// getScannedItemsMap - returns map of all scanned items against type
func (h *healSequence) getScannedItemsMap() map[madmin.HealItemType]int64 {
	h.mutex.RLock()
	defer h.mutex.RUnlock()

	// Make a copy before returning the value
	retMap := make(map[madmin.HealItemType]int64, len(h.scannedItemsMap))
	maps.Copy(retMap, h.scannedItemsMap)

	return retMap
}

// getHealedItemsMap - returns the map of all healed items against type

        };

        // When all entries fail, iterator should be empty
        assertFalse(iterator.hasNext());
        assertNull(iterator.next());
    }

    @DisplayName("Adapter returning null on all entries")
    void adapterReturnsNullOnAll() {
        // Setup
        FileEntry entry1 = mock(FileEntry.class);
        FileEntry entry2 = mock(FileEntry.class);
