Description
This error indicates that a MySQL function, likely a User-Defined Function (UDF) or a built-in function relying on keyring services, encountered an issue because the underlying keyring component failed to perform an operation. This typically happens when MySQL attempts to access secure information managed by a keyring plugin, such as encryption keys or credentials, but the keyring service is unavailable, misconfigured, or returns an error.
