Error when trying to swap PGIE while keeping the same SGIE

• Hardware Platform (Jetson / GPU)
RTXA4000, Driver Version 515.86.01 Dell XPS intel I7-10700 CPU
• DeepStream Version
6.1.1
• JetPack Version (valid for Jetson only)
5.0.2which sample application, the function description)**

Steps to reproduce:
ds-output-tensor-example.zip (96.3 MB)

1. unzip the attached folder, cd into it and build the container using the build script and run it using the run script.
2. Run the ./gst-run.sh script as is (CASE #1) containing the following content:

SGIE="nvinferserver config-file-path=dstensor_sgie1_config.txt !"
#SGIE=""
PGIE="dstest_ssd_nopostprocess.txt"
#PGIE="dstensor_pgie_config.txt"
gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream-6.1/samples/streams/sample_720p.h264 ! h264parse ! \
    nvv4l2decoder ! m.sink_0 nvstreammux name=m ! \
    nvinferserver config-file-path=$PGIE ! \
    $SGIE nvvideoconvert ! nvdsosd ! queue ! nveglglessink

This case doesn’t use the SGIE and it runs, so PGIE works. (bounding boxes are shown in python application but not in gst-launch script).

3. modify the gst-run.sh script to the by uncommenting the second SGIE line and enabling the SGIE (CASE 2)

SGIE="nvinferserver config-file-path=dstensor_sgie1_config.txt !"
SGIE=""
PGIE="dstest_ssd_nopostprocess.txt"
#PGIE="dstensor_pgie_config.txt"
gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream-6.1/samples/streams/sample_720p.h264 ! h264parse ! \
    nvv4l2decoder ! m.sink_0 nvstreammux name=m ! \
    nvinferserver config-file-path=$PGIE ! \
    $SGIE nvvideoconvert ! nvdsosd ! queue ! nveglglessink

The following error is produced:

4 - uncomment the second PGIE line to change the PGIE and rerun the script

SGIE="nvinferserver config-file-path=dstensor_sgie1_config.txt !"
SGIE=""
PGIE="dstest_ssd_nopostprocess.txt"
PGIE="dstensor_pgie_config.txt"
gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream-6.1/samples/streams/sample_720p.h264 ! h264parse ! \
    nvv4l2decoder ! m.sink_0 nvstreammux name=m ! \
    nvinferserver config-file-path=$PGIE ! \
    $SGIE nvvideoconvert ! nvdsosd ! queue ! nveglglessink

This works without error.

Why did case 2 not work, is there something about the PGIE/SGIE pair thats incompatible?
