ONTAP REST API: nas.security_style missing from /storage/volumes when using name filter

[endavis]

When querying /api/storage/volumes with explicit fields including nas.security_style, the field is present in
bulk responses but missing when a name= filter is applied.

Cluster is running: NetApp Release 9.16.1P3

Steps to Reproduce

1. Query all volumes with expensive fields:

   GET /api/storage/volumes?fields=*,autosize,files,nas.path,nas.security_style
   

   Result: nas.security_style is present in the response for each volume record.

2. Query a specific volume by name with the same fields:

   GET /api/storage/volumes?fields=*,autosize,files,nas.path,nas.security_style&name=VOLNAME
   

   Result: nas.security_style is missing from the response.

Expected Behavior

Both queries use the same fields= parameter, so both should return nas.security_style in the response.

Actual Behavior

The bulk query (no name filter) returns nas.security_style, but the name-filtered query does not.

Additional Notes

• Field ordering in the fields= parameter does not affect the behavior — nas.security_style is missing
  regardless of its position in the field list.
• Other expensive fields (autosize, files, nas.path) are returned correctly in both queries.
• This was discovered while building a cache inspection tool that compares filtered -->vs. bulk API responses.
