I believe you are missing curly brackets around the name/value object. i.e.,

{"records":[ {"name":"default", "data":"virt_host2"} ]}

Example:

  • Getting the datagroup (equivalent to 
    tmsh list ltm data-group internal images
    😞
 curl -sku admin: https:///mgmt/tm/ltm/data-group/internal/images

{ kind: 'tm:ltm:data-group:internal:internalstate',
  name: 'images',
  fullPath: 'images',
  generation: 299,
  selfLink: 'https://localhost/mgmt/tm/ltm/data-group/internal/images?ver=11.6.1',
  type: 'string',
  records: [ { name: 'ext1', data: '.ppm' } ]
}
  • Modify (equivalent to 
    modify ltm data-group internal images records replace-all-with {ext1 {data .png} }
    )
 curl -sku admin: https:///mgmt/tm/ltm/data-group/internal/images \
  -X PATCH -H "Content-type: application/json" \
  -d '{"records":[ {"name": "ext1", "data":".png"} ]}'

{ kind: 'tm:ltm:data-group:internal:internalstate',
  name: 'images',
  fullPath: 'images',
  generation: 306,
  selfLink: 'https://localhost/mgmt/tm/ltm/data-group/internal/images?ver=11.6.1',
  type: 'string',
  records: [ { name: 'ext1', data: '.png' } ]
}
