I keep continuously getting elasticsearch.dsl.exceptions.ValidationException: You cannot write to a wildcard index (in python3.12/site-packages/elasticsearch/dsl/document_base.py", line 567, in _get_index) for the example https://github.com/elastic/elasticsearch-py/blob/main/examples/dsl/alias_migration.py.
In what instances wildcard indexes are supported and how?
