- The inconsistency in UVE is due to failure in UVE deletion upon generator disconnect.
  In delrequest.lua, db # is not set before querying the UVE info from redis for deletion
  and this causes the UVEs originated by the generator to remain in redis even after disconnection.
- Added a nil check for ‘href’ attribute in decoded json message
