[illegal_argument_exception] Merging lines into messages resulted in an unacceptably long message. Merged message would have  lines and  characters (limit ). If you have messages this big please increase the value of [line_merge_size_limit]. Otherwise it probably means the timestamp has been incorrectly detected, so try overriding that. Explanation so far: [Using character encoding [UTF-8], which matched the input with [15%] confidence - first [8kB] of input was pure ASCII] [Not NDJSON because there was a parsing exception: [Unexpected character ('#' (code 35)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false') at [Source: (org.elasticsearch.xpack.ml.filestructurefinder.NdJsonFileStructureFinderFactory$ContextPrintingStringReader); line: 1, column: 2]]] [Not XML because there was a parsing exception: [ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog.]] [Not CSV because the first row has fewer than  fields: ] [Not TSV because the first row has fewer than  fields: ] [Not semicolon delimited values because the first row has fewer than  fields: ] [Not vertical line delimited values because the first row has fewer than  fields: ] [Deciding sample is text] [Most likely timestamp format is [yyyy-MM-dd HH:mm:ss]]
