AssetPostprocessor - OnPostprocess* asset not in the AssetDatabase yet

When I import an AudioClip, I want to create a scriptable object that references the clip (and adds other data as well. The problem if I assign the the clip, it doesn't get serialized properly, presumably because it's not in the AssetDatabase yet.
This results in a null.
AssetDatabase.LoadAssetAtPath<AudioClip>(this.assetPath);

Currently I periodically check whether it's there yet and only then I carry on

 for (int i = 0; i < 50; i++)
 {
         clip = AssetDatabase.LoadAssetAtPath<AudioClip>(this.assetPath);
         if (clip)
         {
             break;
         }

         await Task.Delay(50);
 }

This works but feels hacky. Is this a bug or am I missing something? (I'm on 2020.1)

I know this question is from a long while ago, but I'm having this problem now. Were you able to figure it out by chance?

I have switched to a different engine since then actually, so I don't remember. Sorry. I've done a quick search thru my repos and all my code still used smt. like the posted hacky polling snippet, so I don't think I've figured a proper solution/fix. It's been years though, so a newer version of Unity might have fixed it, though seeing you are asking, then maybe not...

Hey thanks anyway for the response. I ended up finding a solution similar to yours, but instead of Task.Delay there's a Unity function that will basically just delay a frame: "EditorApplication.delayCall += () => AssetDatabase.LoadAssetAtPath(this.assetPath)".

I won't list this as an answer, because I'm not sure if this is considered "hacky" as well. But perhaps it'll still be useful if someone else comes across this Question.
