Hey @Ssingh12,

I believe you've run into a known limitation with scripted fields. Your specific script defines an inline function (`compare`), and we recently discovered that this isn't supported when used inside a filter.

See related discussion here: [Getting a no\_viable\_alt\_exception only when trying to filter using a scripted field](https://discuss.elastic.co/t/getting-a-no-viable-alt-exception-only-when-trying-to-filter-using-a-scripted-field/183145/4)
