I using logstash 5.4 to do a query off of elasticsearch running on version 1.7.6, I am not asking for anything regarding a scrollId, what would be the reason this is coming out as an error, it is still outputting basically everything that I need I think.

Error: [400] {"error":"ElasticsearchIllegalArgumentException[Failed to decode scrollId]; nested: IOException[Bad Base64 input character decimal 123 in array position 0]; ","status":400}
