How can I provide validation messages on ShowAcquireDocument?

I have tried to use PostInputContext ValidationErrorFields but not successful. Please guide me on it.

Using PostInputContext.ValidationErrorFields is absolutely the right way to go. This is the validation result I get when I ran a test with the following code snippets:

input.aspx:

...
Input.ShowAcquireDocument("Hero image", "article_hero");
...

post_input.aspx:

if(!context.InputForm.HasField("article_hero")) {
  context.ValidationErrorFields.Add("article_hero", "Please select the asset to link to in the hero display.");
