Base64file uploading to cloudinary is not working

`

func uploadImageToCloudinary(base64str, name string) (*uploader.UploadResult, error) {
cloudinaryURL := os.Getenv("CLOUDINARY_URL")
cloudinaryClient, err := cloudinary.NewFromURL(cloudinaryURL)
if err != nil {
return nil, err
}
formattedString := fmt.Sprintf("data:image/jpeg;base64,%s", base64str)

uploadParams := uploader.UploadParams{
PublicID: name,
UseFilename: true,
UniqueFilename: true,
}

// Upload the Base64 encoded content
result, err := cloudinaryClient.Upload.Upload(context.Background(), formattedString, uploadParams)
if err != nil {
return nil, err
}

return &result, nil
}
