function removeEmpty(input) {
if (typeof input !== "object" || input === null) return undefined;
return Object.entries(input).reduce((acc, [key, value]) => {
if (Array.isArray(value)) {
acc[key] = value.map(item => removeEmpty(item));
return acc;
}
if (typeof value === "object" && value !== null && !(value instanceof Date)) {
if (Object.keys(value).length === 0) return acc;
acc[key] = removeEmpty(value);
return acc;
}
if (value === null) return acc; // comment this line if you have to pass null values.
acc[key] = value;
return acc;
}, {});
