_assetService.UploadFileAsync(query) throws Response status code does not indicate success: 400 (Bad Request) when using OAuth2

[rabehaja-dept]

While using the following code block

``
try
{

            var query = new UploadQuery
            {
                Filepath = tempFilePath,
                BrandId = _brandId, // Use the first available brand for this example
                Name = asset.FileName,
                //CustomParameters = customParameters,
                OriginalFileName = asset.PhysicalFileName,
                Description = UrlEncoder.Default.Encode(asset.ProductName),
            };


            query.MetapropertyOptions = new Dictionary<string, IList<string>>
        {
            { "New_Color_code", new List<string> { asset.ColorCode } },
            { "viewType", new List<string> { asset.ViewType } },
            { "brand", new List<string> { asset.BrandName } },
            { "Collection", new List<string> { asset.Collection } },
            // { "colorCodeDescription", new List<string> { asset.ColorCodeDescription } },
            {"Asset_type", new List<string> { "Images" } },
             {"Asset_Subtype", new List<string> { asset.ViewType} },
            {"17nr",  asset.ProductID },
            {"EAN_UPC",  asset.EAN },
            // {"variantId",  asset.VariantID },
            {"Product_Name_",  new List<string> { asset.ProductName } }

        };


            //upload
             _assetService.UploadFileAsync(query).Wait();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Exception occurred while uploading to Bynder: " + ex.Message);
        }
        finally
        {
            if (File.Exists(tempFilePath))
            {
                File.Delete(tempFilePath);
            }
        }

I receive the following error
Response status code does not indicate success: 400 (Bad Request)

All the variables are fed to the best of my knowledge and to the extent of available documentation. Why is this throwing an issue?

MetapropertyOptions maps to the metaproperty API field https://github.com/Bynder/bynder-c-sharp-sdk/blob/master/Bynder/Sdk/Query/Upload/SaveMediaQuery.cs#L71-L75 for saving media.

From https://bynder.docs.apiary.io/#reference/upload-assets/4-finalise-a-completely-uploaded-file/save-as-a-new-asset

the field metaproperty requires a metaproperty option ID as the key. In your code snippets noticed they are passed as name. Can you try replacing the name of the metaproperties to their corresponding metaproperty ids as well as the option ids?
