"Αuthorization Module Nomatch" message

Hello EMQX Community

I am using EMQX Enterprise 5.3.2 for testing reasons.
The following message appears in the log, without any other problems.

msg: authorization_module_nomatch, ipaddr: {10,50,122,15}, module: emqx_authz_client_info, pub_sub: [action_type: publish, qos: 1, retain: true], topic: SA/A302/HourSync, username: sah2

How can I eliminate this message ?
Does this message have any effect on system performance ?

Thanks in advance
