Collection reference pointing non-existing index creates an exception

[sylvaingaudan]

Collection reference pointing non-existing index creates an exception, while this is a case that should be covered:

• the index exists : the collection reference is provided
• the index does not exists : the collection reference is not provided
  The entire exception stack trace should not be logged, a warning should indicate that the index is not found
