I'm still getting the same error. You'll need to change this line to the following:

const range = { gte: min, lt: max, format: 'epoch_millis' };

Then it will work 😄

if (_.has(existingFilter, 'range')) {
existingFilter.range[event.data.xAxisField.name] = range;
} else if (_.has(existingFilter, 'script.script.params.gte')
&& _.has(existingFilter, 'script.script.params.lt')) {
existingFilter.script.script.params.gte = min;
existingFilter.script.script.params.lt = max;
} else {
const newFilter = buildRangeFilter(
event.data.xAxisField,
range,
event.data.indexPattern,
event.data.xAxisFormatter);
$state.$newFilters = [newFilter];
}
}
};
};
