How to preserve the leading / from the path field

[hailiangzhang]

I understand this cumulus-cnm-to-granule step generates the path field (which is needed by the following ingest-granule step) based on uri field (which comes from the original CNM message).
I noticed that during this step, the leading / will be removed in the path field, e.g.:
"uri": "/data/Aura_OMI_Level2/OMNO2.003/2022/001/..."
will lead to:
"path": "data/Aura_OMI_Level2/OMNO2.003/2022/001"
This causes consistency issues for your ingest pipeline, because our parsing PDR step will eventually generate:
"path": "/data/Aura_OMI_Level2/OMNO2.003/2022/001"
which does include the leading / as shown above.
So, the question is: is there a good reason for CNM cumulus-cnm-to-granule step to remove the leading /? Is there anyway we can keep the leading / easily?
