Expired documents are not allowed by default when supplied for the `
document_scan` task. It is possible to change this behavior by providing the `
allowedExpiration` setting. A positive number allows a document to be expired for the specified number of days, a negative number requires a document to be valid for at least the specified number of days.
**Document should be valid for at least 90 days after expiration date**
