You alias must match the exact name ?

Isnt it missing the "filebeat" part ?

I change it but it's the same issue.
index.lifecycle.rollover_alias [test-alias-rollover] does not point to index [filebeat-7.4.2-ker-roolover-000001]

I found this problems. alias test-alia rollover pint to rollover-00001 and rollover-00002.
Created other index but not fill it. Continue to fill rollover-000001
