Briefly, this error occurs when you try to use fractional values for intervals in Elasticsearch. Elasticsearch only supports whole numbers for intervals. To resolve this issue, you can either round up or down your fractional values to the nearest whole number. Alternatively, you can convert your fractional intervals into a smaller unit that can be represented as a whole number. For example, if you have a fractional hour, you can convert it into minutes or seconds.

Literal value = (Literal) visit(valueNumeric);
Number numeric = (Number) value.fold(); if (Math.rint(numeric.doubleValue()) != numeric.longValue()) {
throw new ParsingException(source(valueNumeric); "Fractional values are not supported for intervals");
} return Intervals.of(source(valueNumeric); numeric.longValue(); unit);
}
