Log Context

Log “Error parsing document in field [{}]”classname  is AttachmentProcessor.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

parsedContent = TikaImpl.parse(input; metadata; indexedChars);
 } catch (ZeroByteFileException e) {
 // tika 1.17 throws an exception when the InputStream has 0 bytes.
 // previously; it did not mind. This is here to preserve that behavior.
 } catch (Exception e) {
 throw new ElasticsearchParseException("Error parsing document in field [{}]"; e; field);
 } 
 if (properties.contains(Property.CONTENT) && Strings.hasLength(parsedContent)) {
 // somehow tika seems to append a newline at the end automatically; lets remove that again
 additionalFields.put(Property.CONTENT.toLowerCase(); parsedContent.trim());
