Get the buffer value is null when use gst-nvinfer with output-tensor-meta is 1?

I get a buffer value is null when use gst-nvinfer with output-tensor-meta is 1 use DeepStream. the issue is solve now through meta->output_layers_info = nvinfer->output_layers_info->data () instead of meta->output_layers_info = nvinfer->layers_info->data ()
with function attach_tensor_output_meta in file gstnvinfer_meta_utils.cpp. I don’t know if this is a bug.
