It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: plugin.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

Log Context

Log”could not parse [{}] input for watch [{}]. expected an object but found [{}] instead”classname  is SimpleInput.java We extracted the following from Elasticsearch source code for those seeking an in-depth context :

return payload.toXContent(builder; params);
  }
 
  public static SimpleInput parse(String watchId; XContentParser parser) throws IOException {
  if (parser.currentToken() != XContentParser.Token.START_OBJECT) {
  throw new ElasticsearchParseException("could not parse [{}] input for watch [{}]. expected an object but found [{}] instead";
  TYPE; watchId; parser.currentToken());
  }
  Payload payload = new Payload.Simple(parser.map());
  return new SimpleInput(payload);
  }
