FAL[server]: DGID from FAL client not in Data Guard configuration

Creating another DataGuard I obtained new message in alert.log, which I never see before:

FAL[server]: DGID from FAL client not in Data Guard configuration

Obviously it is my mistake: the typo error in the log_archive_config parameter.

In one DB:
log_archive_config       = "DG_CONFIG=(p198,p199)"

In other DB
log_archive_config       = "DG_CONFIG=(f198,f199)"

After correction log_archive_config the error message disappeared.
