Logstash unable to map field to es

Elastic Stack Logstash
1

I am using a multiline config in filebeat to send logs as one line, not sure if that is the cause of this.

I am currently getting this error when indexing certain log files.

response=>{"index"=>{"_index"=>"filebeat-2018.08.08", "_type"=>"log", "_id"=>"AWUbQVOf54TmqKKkRQHo", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"object mapping for [source] tried to parse field [source] as object, but found a concrete value"}}}}

Here is the full output.

Here is the field mapping for source

"source": {
            "properties": {
              "class": {
                "type": "text",
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              }

LS creates a new index everyday for that days data. I ran into this yesterday and deleted the index and then it processed the record but that was a temporary fix.

I would much appreciate pointers on how to manage this. Thanks!

For some reason the source field is mapped as an object (with a class subfield) and then you can't index documents where source contains a concrete value. Which documents contain source.class fields? Are those incorrect? Or are the documents where source is a concrete value incorrect? Both can't be right.

Thank you for taking the time to reply magnusbaeck! I am very new to all things ELK so I am attempting to decipher your questions. I will update the thread once I have something of value.

This may be helpful as well??

{
  "_index": "filebeat-2018.08.09",
  "_type": "log",
  "_id": "AWUc16lD54TmqKKkR8pR",
  "_version": 1,
  "_score": null,
  "_source": {
    "offset": 1809078,
    "level": "ERROR",
    "profile": "tst",
    "logger": "com.blah.ems.search.solr.agile.AgileDocumentIndexer",
    "module": "api",
    "input_type": "log",
    "source": {
      "file": "AgileDocumentIndexer.java",
      "method": "index",
      "class": "com.blah.ems.search.solr.agile.AgileDocumentIndexer",
      "line": 68
    },

OK, so in one you have

"source" : "/local/mnt/logs/filebeat/apps/solr/solr-qdisk-new.log"

and in the other you have

"source": {
  "file": "AgileDocumentIndexer.java",
  "method": "index",
  "class": "com.blah.ems.search.solr.agile.AgileDocumentIndexer",
  "line": 68
}

You cannot have the source field be an object in some documents and text in other documents in the same index. You would have to use multiple indexes.
