I installed elasicsearch 5.0.1 with ingest attachment and tried indexing pdf in elasticsearch from shell script using below command ``` #!/bin/ksh var=$(base64 sample.pdf | perl -pe 's/\n/\\n/g') var1=$(curl -XPUT 'http://localhost:9200/my_index5/my_type/my_id?pipeline=attachment&pretty' -d' { "data" : "'$var'" }') echo $var1 ``` i got an error as below ``` { "error" : { "root_cause" : [{ "type" : "exception", "reason" : "java.lang.IllegalArgumentException: ElasticsearchParseException[Error parsing document in field [data]]; nested: IllegalArgumentException[Illegal base64 character a];", "header" : { "processor_type" : "attachment" } } ] ``` I am encoding the pdf to base64 but still i m getting the error. Can i please get help to resolve the same ? ---

Hi David, It prints the error .. ``` { "error" : { "root_cause" : [{ "type" : "exception", "reason" : "java.lang.IllegalArgumentException: ElasticsearchParseException[Error parsing document in field [data]]; nested: IllegalArgumentException[Illegal base64 character a];", "header" : { "processor_type" : "attachment" } } ] ``` ---

Ha sorry. I meant can you print the generated curl command so we can see how it looks before it gets executed? ---

I see. I'd remove all `\n` chars here. So something like: `s/\n//g` ---

Thanks a lot David .. It worked ... I indexed that pdf. But when i tried indexing another pdf document which is longer in size, i got an error saying ``` curl: /usr/bin/curl: cannot execute [Argument list too long] ``` Is there any limit for the document size ? or i need to do it in any other way ? Please help ---

May be it's a problem with curl? Also there is a default limit in ES which is IIRC 100mb per HTTP request. ---
