internal: expects an array error with array type

[happy-machine]

Hi really struggling with this would really appreciate your help

My parent resolver is giving me the error: internal: expects an array

I am iterating through the fields in the dynamic version .. this is a simplified version where im returning a hard coded value simulating what im expecting to return:

  for (key, val) in fields.iter() {
    let field = Field::new(
        key.to_string(),
         TypeRef::named_list(TypeRef::STRING),
        |ctx:ResolverContext| FieldFuture::new(async move {
          Ok(Some(Value::from(vec!("boom", "town"))))
        })
    );
    model = model.field(field);
  }

I can't return an array literal because the trait bound async_graphql::Value: std::convert::From<[&str; 2]> is not satisfied so i can't easily test if the problem is it expects an actual array rather than a vec

Can you help?

You need to convert all elements to Value first

Ok(Some(Value::List(
    vec!["boom", "town"].into_iter().map(Value::from).collect(),
)))

Thanks for your quick response sunli : )

I've just tried that, with:

Ok(Some(Value::List(vec!("boom", "town").into_iter().map(Value::from).collect())))

And that gives the same error:
"internal: expects an array"

This also doesn't work although both pass Rust analyser Ok(Some(Value::List(vec!(Value::from("testing".to_string()), Value::from("testing".to_string())))))

Sorry I was wrong😂, the list resolver does not recognize Value::List, you should do it like this:

FieldValue::list(vec!["boom", "town"].into_iter().map(FieldValue::value))

This example can help you:

I will support Value::List in v5.0.2
