Hi,
I using filebeat via logstash and normaly connect to Elasticsearch. In normal connect is ok but via logstash I have a problem:
illegal_argument_exception at shard 0 index filebeat-8.1.2-2022.04.01 node x1NX6Z2sRz2pH9YrYLI70w
Type
illegal_argument_exception
Reason
Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [host.hostname] in order to load field data by uninverting the inverted index. Note that this can use significant memory.
