@Prop() schemaType on Map not working about mongoose

Please provide a minimum reproduction repository (Git repository/StackBlitz/CodeSandbox project).

I see, you cannot use raw, which makes sense

any news about this topic?

I tried to make the same question in discord with no answer.
this is the question:

to store a { [key: string]: string } object following the docs I've set my graphql field as

@Field(() => GraphQLJSON)
name: JSON;

(using JSON scalar) and on the schema the Mongoose Object is defined like

@Prop({ type: SchemaTypes.Mixed })

this is the only working configuration I've come up with, but this doesn't involve any type of schema validation.
I expected I could do something like @Prop({type:Map, of: String})or @Prop(raw({type:Map, of: String})) but I get casting error:

validation failed: name: Cast to Map failed for value "[Object: null prototype] (type object) at path because of "TypeError" nestjs mongoose

is this expected?
