Use the below code to fix the problem, We will fix it in abp framework.

Configure<AbpBlobStoringOptions>(options =>
{
    options.Containers.Configure<PhotoContainer>(container =>
    {
        container.UseMinio(minio =>
        {
            minio.EndPoint = "localhost:9000"; // your minio endPoint
            minio.AccessKey = "minioadmin"; // your minio accessKey
            minio.SecretKey = "minioadmin"; // your minio secretKey
            minio.BucketName = "photo";

            minio.CreateBucketIfNotExists = true;
        });

        container.ProviderType = typeof(MyMinioBlobProvider);
    });
}

using Minio;
using Volo.Abp.BlobStoring;
using Volo.Abp.BlobStoring.Minio;

namespace KlicKlac;

public class MyMinioBlobProvider : MinioBlobProvider
{

    public MyMinioBlobProvider(
        IMinioBlobNameCalculator minioBlobNameCalculator,
        IBlobNormalizeNamingService blobNormalizeNamingService)
        : base(minioBlobNameCalculator, blobNormalizeNamingService)
    {
    }

    protected override MinioClient GetMinioClient(BlobProviderArgs args)
    {
        var configuration = args.Configuration.GetMinioConfiguration();

        var client = new MinioClient()
            .WithEndpoint(configuration.EndPoint)
            .WithCredentials(configuration.AccessKey, configuration.SecretKey);

        if (configuration.WithSSL)
        {
            client.WithSSL();
        }

        return client.Build();;
    }
}
