### Description Fixes issue #15135 Result  Also this works with other commands: min, max, sum, product, avg... ### User-Facing Changes Error is returned, instead of console completely blocked and having to be killed I chose "Incorrect value", because commands accept inputs of range type, just cannot work with unbounded ranges. ### Tests + Formatting - ran cargo fmt, clippy - added tests
