Since 7.10.1 the watcher expand_wildcards property has accepted and returns an array for expanded_wildcards. This broke in our existing representation of IndicesOptions during deserialisation. This change is breaking but now supports either a single string value or an array in the JSON response.
I've added an additional test to run on 7.10.1 and later to PUT and GET a watch with multiple
expand_wildcards
.I've updated existing tests to add the optional
allow_no_indices
property due to a regression in 7.10.1 and 7.10.2 which meant missing optional fields caused a validation error on the server. This ensures the tests can run against any 7.10.x version.
