AnyType IDictionary serialize like JSON

[steveoh]

Describe the bug

IDictionary<string, object> serialization as AnyType is weird.

To Reproduce

With the following query and output type

public class Query
{
    public Thing Query() => new Thing { Junk = new Dictionary<string, object> {{ "name", "yo" }}};
}

public class Thing {
  [GraphQLType(typeof(AnyType))] public IDictionary<string, object> Junk { get; set; }
}

An error is thrown EXEC_INVALID_LEAF_VALUE when querying.

If I change the dictionary type to IDictionary<string, string> then the serialization is weird

{
  "junk": [
    {
       "key": "name",
       "value": "yo"
    }
  ]
}

If I create a constructor to take the dictionary<string, object> and iterate over its values calling ToString then I get the expected result and that is weird.

foreach(var key in Junk.Keys) {
   Junk[key] = Junk[key].ToString();
}

But, I get the expected result

{
  "junk": {
    "name": "yo"
   }
}

Expected behavior

I expect IDictionary<string, object> to serialize like json

Desktop (please complete the following information):

• OS: macos
• Version: 10.15.7

I'm also seeing this issue.

OS: macos Version: 11.3.0

[scottcollins]

I am as well.

Windows 10 Visual studio 2019 Version 11.3.0

partial record CountryDto
{
    [GraphQLType(typeof(AnyType))]
    public IDictionary<string, string> Provinces { get; init; } = null!;
}

Results in the following if I run the query in Banana Cake Pop

{
  "data": {
    "country": {
      "name": "United States",
      "abbreviation": "us",
      "provinces": [
        {
          "key": "AL",
          "value": "Alabama"
        },
        {
          "key": "AK",
          "value": "Alaska"
        },

[glen-84]

I added this test:

        [Fact]
        public async Task Output_Return_Dictionary()
        {
            // arrange
            ISchema schema = SchemaBuilder.New()
                .AddQueryType(d => d
                    .Name("Query")
                    .Field("foo")
                    .Type<AnyType>()
                    .Resolve(_ => new Dictionary<string, object> {
                        { "number", 123 },
                        { "dateTime", DateTime.UnixEpoch } }))
                .Create();

            IRequestExecutor executor = schema.MakeExecutable();

            // act
            IExecutionResult result = await executor.ExecuteAsync("{ foo }");

            // assert
            result.ToJson().MatchSnapshot();
        }

But the snapshot looks correct ...

{
  "data": {
    "foo": {
      "number": 123,
      "dateTime": "1970-01-01T00:00:00.000Z"
    }
  }
}

So I'm not sure what's going on in my case (and the case of the OP and others).

I'm using this in my Error type.

I need to look into it more.

Hello,

Do you think you will work on this subject ? I have to return yaml content files from my api (I parse the files and load them into Dictionary<string, object>) and need to have the capacity.

Maybe I found a workaround. Don't expose a Dictionary but a IReadOnlyDictionary as the AnyType ParseValue will do :

 if (value is IReadOnlyDictionary<string, object> dict)
            {
                var fields = new List<ObjectFieldNode>();
                foreach (var field in dict)
                {
                    fields.Add(new ObjectFieldNode(
                        field.Key,
                        ParseValue(field.Value, set)));
                }
                return new ObjectValueNode(fields);
            }

By changing my Dictionary type to IReadOnlyDictionary, I had the expected result

Before :

{
"capacities":[{"key":"SubnetProvider","value":true}]
}

After :

{
"capacities":{"SubnetProvider":true}
}

thank you

[ernestfolch]

I have same error and the workaround exposing the Dictionary as IReadOnlyDictionary it doesn't work in my case, I'm still getting key/value pairs.

[corinaivanov]

The same thing happens to me, even after changing to IReadOnlyDictionary.

[glen-84]

Trying to debug this a bit, and for whatever reason, the runtime type is a KeyValuePair – that seems odd, shouldn't it be a dictionary?

[Soundman32]

A dictionary is basically ICollection<KeyValuePair<K,V>>.

[glen-84]

A dictionary is basically ICollection<KeyValuePair<K,V>>.

Right, but KeyValuePair is the element type, not the type itself.

[michaelstaib]

Use our new JsonType. Video coming out soon ...

[glen-84]

@michaelstaib

Use our new JsonType. Video coming out soon ...

If I do ...

    [GraphQLType<JsonType>]
    public required Dictionary<string, string> Fields { get; init; }

I get:

JSON cannot serialize the given value.

I don't think that the JSON type solves the original issue of serializing dictionaries specifically, not just any dynamic data.

If JSON serializes a Dictionary<string, object> (or <string, string>) as an object/map, one might expect that to be the default behaviour in Hot Chocolate.

[michaelstaib]

I have reopened this to investigate the issue @glen-84 still has with the Any and JSON.

[glen-84]

I tested the issue in the OP, and I cannot reproduce it in HC 13.0.2.

Michael has said that only <string, object> is supported, not <string, string>.

@RubcovMindbox @ernestfolch @corinaivanov

Which type and generic arguments are you using?

I encountered similar issue.

For me it was JToken and ExpandoObject issues.

I had to convert JToken to Dictionary recursively instead of just using .ToObject<Dictionarty<string, object?>>

And I had to convert ExpandoObject to ReadOnlyDictionary. It's a dictionary already, but it seems HC expects only ReadOnly ones in ObjectToDictionaryConverter

@michaelstaib Does it make sense to add IDictionary in addition to IReadOnlyDictionary in ObjectToDictionaryConverter?

    private void VisitObject(
        object obj,
        Action<object> setValue,
        ISet<object> processed)
    {
        if (processed.Add(obj))
        {
            var dict = new Dictionary<string, object>();
            setValue(dict);

            if (obj is IReadOnlyDictionary<string, object> d)
            {
                foreach (KeyValuePair<string, object> item in d)
                {
                    Action<object> setField = v => dict[item.Key] = v;
                    VisitValue(item.Value, setField, processed);
                }
            }
            else
            {
                foreach (PropertyInfo property in GetProperties(obj))
                {
                    string name = property.GetGraphQLName();
                    object value = property.GetValue(obj);
