Snapshot Management sends notification false positive

[DominikMoelter]

I'm using a snapshot policy which was created via Opensearch Dashboards that backups a bunch indices. If a policy run fails I want to get a email notification. The policy runs every morning. The status of every run was successfull but I receive every morning a mail regarding to a failed policy run.

Mail:

}

As you can see in the policy explain the both creation of new snapshot and deletion of new snapshot were successfull.
Any ideas why the mail is nevertheless sent?

Also checked the logs as mentioned in the mail. Log looks OK.
