Briefly, this error occurs when Elasticsearch is unable to retrieve the maximum file size due to an issue with the Java Native Access (JNA) library. This could be due to incorrect permissions, a missing library, or an incompatible version of the JNA library. To resolve this issue, you can try updating the JNA library to the latest version, ensuring the library is correctly installed and accessible, or checking and correcting the file permissions.
