Briefly, this error occurs when Elasticsearch fails to parse a condition for a watch. This could be due to incorrect syntax, invalid data type, or a non-existent field in the condition. To resolve this, ensure that the condition syntax is correct, the data types match, and the field exists in the index. Also, check if the compared value is in the correct format and compatible with the field type. If the error persists, consider debugging with a simpler condition to isolate the issue.

Log Context
Log “could not parse [{}] condition for watch [{}]. compared value for [{}] with” class name is CompareCondition.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
throw new ElasticsearchParseException("could not parse [{}] condition for watch [{}]. unknown comparison operator " +
"[{}]"; TYPE; watchId; parser.currentName());
}
token = parser.nextToken();
if (op.supportsStructures() == false && token.isValue() == false && token != XContentParser.Token.VALUE_NULL) {
throw new ElasticsearchParseException("could not parse [{}] condition for watch [{}]. compared value for [{}] with " +
"operation [{}] must either be a numeric; string; boolean or null value; but found [{}] instead"; TYPE;
watchId; path; op.name().toLowerCase(Locale.ROOT); token);
}
value = XContentUtils.readValue(parser; token);
token = parser.nextToken();
