Question Make coroutine wait for async inside a try clause

I hade this methode inside a coroutine

wrapper.PutToDBAsync(newVenue);

I've recieved the warning
"Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call."

in most places I've changed it to

Code (CSharp):

1.                 Task task = wrapper.PutToDBAsync(newEntry);
2.                 yield return new WaitUntil(()=>task.IsCompleted);

And it worked fine.

But in 1 place I wanted to perform a 'try' around it

Code (CSharp):

1.             try
2.             {
3.                 if (newEntry != null)
4.                 {
5.                     wrapper.PutToDBAsync(newEntry);
6.                 }
7.                 else
8.                 {
9.                     GameStaticData.LogError($"new {entry.name} is null");
10.                 }
11.             }

And I cannot yield inside a 'try' clause.

Any Idea how to bypass it?

 

Why do you have to call return yield inside the try? Cant you just put it outside? Maybe im missing why this is a problem.

 

Idea here with some extension methods:

Code (CSharp):

1.  
2. using System;
3. using System.Collections;
4. using UnityEngine;
5.  
6. public class ExampleClass: MonoBehaviour
7. {
8.     readonly int[] _values = new int[] { 1, 2, 3, 4 };
9.  
10.     private void Update()
11.     {
12.         //Right click to start a coroutine which won't catch an error
13.         if (Input.GetMouseButtonDown(0))
14.             StartCoroutine(Routine(4).TryYield((error) => Debug.LogWarning($"Error catched: {error.Message}")));
15.  
16.         //Right click to start a coroutine which will catch an error
17.         if (Input.GetMouseButtonDown(1))
18.             StartCoroutine(Routine(5).TryYield((error) => Debug.LogWarning($"Error catched: {error.Message}")));
19.     }
20.  
21.     IEnumerator Routine(int length)
22.     {
23.         for(int i = 0; i < length; i++)
24.         {
25.             Debug.Log(_values[i]);
26.             yield return new WaitForSeconds(0.5f);
27.         }
28.     }
29. }
30.  
31.  
32.  
33. public static class TryYieldExtension
34. {
35.     public static IEnumerator TryYield(this IEnumerator enumerator, Action<Exception> catchCallback = null) => TryYield<Exception>(enumerator, catchCallback);
36.     public static IEnumerator TryYield<T>(this IEnumerator enumerator, Action<T> catchCallback = null) where T : Exception
37.     {
38.         while (true)
39.         {          
40.             try
41.             {
42.                 if (!enumerator.MoveNext())              
43.                     break;                              
44.             }
45.             catch (T error)
46.             {
47.                 catchCallback?.Invoke(error);
48.                 yield break;
49.             }
50.             yield return enumerator.Current;
51.         }      
52.     }
53. }
