How It Affects Your App
This error indicates that the InnoDB Full-Text Search auxiliary table is not in the expected hexadecimal format. This can cause the application to be unable to perform full-text searches, as the auxiliary table is necessary for this feature. Additionally, the application may be unable to start up, as the error prevents the InnoDB engine from initializing. This can lead to data loss and application downtime, as the application will be unable to process requests until the issue is resolved.
