Basically, im trying to get the []byte from a image, using this functions:

func getAttachmentData(fileID string) ([]byte, errors.Error) {
    path := fmt.Sprintf("../../../../uploads/%s", fileID)

    if _, err := os.Stat(path); os.IsNotExist(err) {
        return nil, errors.NewUnexpected()
    }

    file, err := os.Open(path)
    if err != nil {
        return nil, errors.NewUnexpected()
    }
    defer file.Close()

    fileInfo, err := file.Stat()
    if err != nil {
        return nil, errors.NewUnexpected()
    }

    fileHeader := &multipart.FileHeader{
        Filename: fileInfo.Name(),
        Size:     fileInfo.Size(),
    }

    fileBytes, err := convertFileHeaderToBytes(fileHeader)
    if err != nil {
        return nil, errors.NewUnexpected()
    }

    return fileBytes, nil
}

But, when i run the code, i get an error saying that cannot find the file.
The code struct is like:

The code is in:

src/infra/repository/attach/attachment.go

and the image is in:

uploads/

I tried to use the absolute path, remove some of the “../”, change the file, but the error persists. All i want, is to make this function work fine.
