When checking `if (entry.id === kAuthenticationFailedLogId)`, we are incorrectly trying to access `attr.error.code` of the entry object. However, the error field is a string, not an object with a code key.

Example of a log entry:

{"attr": \{"error": "AuthenticationAbandoned: Authentication session abandoned, client has likely disconnected"}

We should check whether the error contains specific substring such as "AuthenticationAbandoned".
