I have no experience with Nikon DSLR driver, but I don't think you can combine client upload mode and target set to memory card. You should probably use either of the two. Note, that saving images directly to a memory card installed in your DSLR will disable majority of Ekos functionalities, which require images available to the system - either locally or remotely.

Thanks.Kaczorek
I'm not sure have i tried that option before cause indilib.org/devices/ccds/gphoto.html is mentioned ""Nikon is officially supported under GPhoto but the level of features supported is less than that of Canon cameras. For bulb exposures to work, you must set Capture Target to SD Card. By default it is set to Internal RAM which is problematic in Nikon cameras."

Anyway I tried also "internal RAM" option but same error occured

Can you try local instead of client? Make sure that the directory is set in Ekos CCD. The strange thing is that your log says "Downloading /" even though you have /home/astroberry directory set in Ekos.

Already tried that, no help
Actually that's what I wondered too.
I think this is the part of code where error occures:
void gphoto_set_upload_settings(gphoto_driver *gphoto, int setting)
{
    gphoto->upload_settings = setting;
}
 
static int download_image(gphoto_driver *gphoto, CameraFilePath *fn, int fd)
{
    int result;
    CameraFileInfo info;
 
    strncpy(gphoto->filename, fn->name, sizeof(gphoto->filename));
 
    if (fd < 0)
    {
        result = gp_file_new(&gphoto->camerafile);
        DEBUGFDEVICE(device, INDI::Logger::DBG_DEBUG, "gp_file_new result: %d", result);
    }
    else
    {
        result = gp_file_new_from_fd(&gphoto->camerafile, fd);
        DEBUGFDEVICE(device, INDI::Logger::DBG_DEBUG, "gp_file_new_from_fd result: %d", result);
    }
 
    DEBUGFDEVICE(device, INDI::Logger::DBG_DEBUG, "Downloading %s/%s", fn->folder, fn->name);
 
    result = gp_camera_file_get(gphoto->camera, fn->folder, fn->name, GP_FILE_TYPE_NORMAL, gphoto->camerafile,
                                gphoto->context);
 
    DEBUGFDEVICE(device, INDI::Logger::DBG_DEBUG, "Downloading result: %d", result);
 
    if (result != GP_OK)
    {
        DEBUGFDEVICE(device, INDI::Logger::DBG_ERROR, "Error downloading image from camera: %s",
                     gp_result_as_string(result));
        gp_file_free(gphoto->camerafile);
        gphoto->camerafile = NULL;
        return result;
    }

I think there should be directory and file name after "Downloading /", right?
