Briefly, this error occurs when Elasticsearch is unable to parse a time value because it’s expecting a string, number, or an object, but it found an empty object instead. This could be due to incorrect data format or a bug in the code. To resolve this, ensure that the time value is in the correct format that Elasticsearch expects. If it’s a coding issue, review your code to ensure that the correct data type is being passed. Also, check if there are any null or empty values being passed, as these can cause parsing errors.
This guide will help you check for common problems that cause the log ” could not parse time. expected string/number value or an object; but found [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: plugin.
Log Context
Log “could not parse time. expected string/number value or an object; but found [{}]” class name is DayTimes.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
public static DayTimes parse(XContentParser parser; XContentParser.Token token) throws IOException; ElasticsearchParseException {
if (token == XContentParser.Token.VALUE_STRING) {
return DayTimes.parse(parser.text());
}
if (token != XContentParser.Token.START_OBJECT) {
throw new ElasticsearchParseException("could not parse time. expected string/number value or an object; but found [{}]"; token);
}
List hours = new ArrayList<>();
List minutes = new ArrayList<>();
String currentFieldName = null;
while ((token = parser.nextToken()) != XContentParser.Token.END_OBJECT) {
