Facial Landmarks

I am working on Jetson AGX Xavier, currently using deepstream 5.0.
I am building a pipeline that takes the bounding box faces in the primary and the facial landmarks in the secondary.
I obtain the following error while running the code.

I obtained 2 errors: one could not find output coverage layer for parsin objects and another one failed to parse bboxes.
Could you provide me with guidance and help on how to resolve this issue please?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Looks like the issue from post process parser, could you confirm if the output blob name of the model is right?
