$lte argument cannot be a Range: #

Error message

$lte argument cannot be a Range: #{Errors::InvalidQuery.truncate_expr(condition)}

What it means

Raised by Mongoid::Matcher::Lte.matches? when the $lte condition is a Range. Ranges cannot be meaningfully compared with <= as a single predicate in memory and are rejected as the $lte condition; the faulting input is the Range condition.

Solutions

1. Pass a scalar to $lte, e.g. the range's last element
2. Use $gte/$lte on scalar bounds for inclusive range matching

When it happens

Trigger: Thrown at lib/mongoid/matcher/lte.rb:21 when the library encounters an invalid state.
