According to the graph, my gstdsexample is before tiled_display_tiler. gstnvdsosd plugin is after tiler.
I need to shift my gstdsexample to after gstnvdsosd.
So what I did was put gstdsexample after gstnvdsosd.

if (config->osd_config.enable) {
    if (!create_osd_bin (&config->osd_config, &instance_bin->osd_bin)) {
      goto done;
    }

    gst_bin_add (GST_BIN (instance_bin->bin), instance_bin->osd_bin.bin);

    NVGSTDS_LINK_ELEMENT (instance_bin->osd_bin.bin, last_elem);

    last_elem = instance_bin->osd_bin.bin;
  }
  
  if (config->dsexample_config.enable) {
    // Create dsexample element bin and set properties
    if (!create_dsexample_bin (&config->dsexample_config,
            &pipeline->dsexample_bin)) {
      goto done;
    }
    // Add dsexample bin to instance bin
    gst_bin_add (GST_BIN (pipeline->pipeline), pipeline->dsexample_bin.bin);

    // Link this bin to the last element in the bin
    NVGSTDS_LINK_ELEMENT (pipeline->dsexample_bin.bin, last_elem);

    // Set this bin as the last element
    last_elem = pipeline->dsexample_bin.bin;
  }

I have the following errors.

Is it because of I need to put gstqueue in between?
How can I solve the issue?

The whole function is as follows.
