Hello, everyone! We have strange error in our elasticsearch log:
[2020-11-20T15:41:59,294][ERROR][c.a.o.s.f.OpenDistroSecurityFilter] [<node_name>] Unexpected exception [_license] InvalidIndexNameException[Invalid index name [_license], must not start with '_'.] org.elasticsearch.indices.InvalidIndexNameException: Invalid index name [_license], must not start with '_'.
Seems that index which would contain "_license" string in its name doesn't exists. Does anyone know how to deal with this?
