Briefly, this error occurs when Elasticsearch encounters multiple services that match a single wildcard. This can happen when there are multiple indices or services with similar names. To resolve this issue, you can either rename the indices or services to make them unique, or specify the exact name of the index or service you want to use, instead of using a wildcard. Another solution is to adjust your search query to be more specific, thus avoiding the wildcard match.
