Briefly, this error occurs when Elasticsearch is unable to parse a date claim due to incorrect format or data type. This could be because the date format in the claim doesn’t match the expected format, or the claim might not be a date at all. To resolve this issue, ensure that the date claim is in the correct format as expected by Elasticsearch. If the claim is not a date, you may need to convert it to a date or adjust your query to treat it as a different data type.
