Motivation

Query parameter serialization should not drop valid falsy values such as 0 or false. The previous implementation could omit these values when building URLSearchParams, leading to incorrect requests (e.g. limit=0 or boolean flags not being sent).

Solution

• Updated serialize all values except null and undefined (including 0, false, and empty strings).
• Preserved array handling while ensuring array items also skip only null/undefined.
• Added a unit test: verifies the generated request URL includes limit=0 and include=false.
