Hey team 👋

Hope this is the right place to open Golang generation issues, today I faced a weird issue that I will try to describe below.

It seems that the generator produces a broken Golang code when trying to parse a body made by an array of scalars.

paths:
  /posts:
    post:
      description: 'Create post'
      requestBody:
        required: true
        content:
          application/json:
            schema:
              type: array
              items:
                format: int32
                type: integer
      responses:
        '201':
          description: Created
          content:
            application/json:
              schema:
                type: array
                items:
                  format: int32
                  type: integer

The generated ToPostRequestInformation is something like:

// ToPostRequestInformation create post
// returns a *RequestInformation when successful
func (m *PostsRequestBuilder) ToPostRequestInformation(ctx context.Context, body []int32, requestConfiguration *PostsRequestBuilderPostRequestConfiguration)(*i2ae4187f7daee263371cb1c977df639813ab50ffa529013b7437480d1ec0158f.RequestInformation, error) {
    requestInfo := i2ae4187f7daee263371cb1c977df639813ab50ffa529013b7437480d1ec0158f.NewRequestInformationWithMethodAndUrlTemplateAndPathParameters(i2ae4187f7daee263371cb1c977df639813ab50ffa529013b7437480d1ec0158f.POST, "{+baseurl}/posts", m.BaseRequestBuilder.PathParameters)
    if requestConfiguration != nil {
        requestInfo.Headers.AddAll(requestConfiguration.Headers)
        requestInfo.AddRequestOptions(requestConfiguration.Options)
    }
    requestInfo.Headers.TryAdd("Accept", "application/json")
    requestInfo.SetContentFromScalarCollection(ctx, m.BaseRequestBuilder.RequestAdapter, "application/json", body)
    return requestInfo, nil
}

The issue is that requestInfo.SetContentFromScalarCollection(ctx, m.BaseRequestBuilder.RequestAdapter, "application/json", body) cannot receive body (which is a []int32) as it is expecting a []interface{} type which is not allowed [1].

Maybe I missed something or I am doing something wrong (in that case, please let me know) but I think that the openapi is a valid one, therefore I am expecting a valid generated code.

How to reproduce the issue

To reproduce the issue I took the posts quickstart from the doc and I simply modified it to have a body made by a list of scalars.

1. Clone my sample repo: https://github.com/lampajr/kiota_posts
2. Run kiota generate -l go -c PostsClient -n kiota_posts/client -d ./posts-api.yaml -o ./client
