Cannot set server parameter "error_server_log_file" ON.

[matsunotsuma]

I cannot set server parameter "error_server_log_file" ON using either Azure portal or Azure CLI.
https://learn.microsoft.com/en-us/azure/mysql/flexible-server/concepts-error-logs

Azure CLI Message is as follow.

(ConfigurationReadOnly) The configuration(s) 'error_server_log_file' is(are) read-only for 0 server version 8.0.21.
Code: ConfigurationReadOnly
Message: The configuration(s) 'error_server_log_file' is(are) read-only for 0 server version 8.0.21.

Best regards.
