This error occurs when an AWS KMS error is encountered while using the MySQL Keyring AWS UDF.

How It Affects Your App

This error indicates that the application is unable to access the AWS Key Management Service (KMS) for the MySQL User Defined Function (UDF). This means that the application will not be able to use the UDF to access the KMS, which could lead to data security issues. Additionally, the application may not be able to access the data stored in the KMS, which could lead to data loss or corruption. Finally, the application may not be able to perform certain operations that require access to the KMS, which could lead to unexpected behavior or errors.
