ObjectSerializer not working for single object

[SahSantoshh]

fast_jsonapi version: 1.5
The object serializer is working fine if an array of objects is passed to serializer:

def index
    contents = Content.page params[:page]
    render json: ContentSerializer.new(contents)
end

But it doesn't work for single object

def show
   options = {}
   options[:include] = %i[content_texts image_labels]
   render json: ContentSerializer.new(@content).serializable_hash, status: 200
end

Since you haven't posted any issue backtrace or error.

I am guessing the Content model has :size attribute or method defined on it which causes the issue.

Try to use the new repo which doesn't have this issue
