By creation of a new pipeline, the following error began to pop up on the filebeat side:
{"type":"mapper_parsing_exception","reason":"object mapping for [host] tried to parse field [host] as object, but found a concrete value"}
I thought it might be something like the breaking change with the field host even though logstash is not used but instead filebeat feeds directly into the ingest pipeline.
I first tried to add the processor the the filebeat.yml in order to drop the field, but there were no changes observed.
I then tried removing the field from the pipeline, but now I'm becoming the following error:
{"type":"illegal_argument_exception","reason":"field [host] not present as part of path [host]"}
In the pipeline, or the filebeat.yml there is no mention of the field host, so I'm wondering, where does this host field comes from which causes the conflict.
