xianyu search min-price cannot be greater than max-price

Error message

xianyu search min-price cannot be greater than max-price

What it means

After both price bounds are parsed, the CLI checks that min-price <= max-price. A reversed range cannot be sent to Goofish's server-side price filter (priceRange:<min>,<max>;), so an ArgumentError is thrown listing both received values.

Solutions

Swap the values: --min-price 1000 --max-price 5000
Omit one bound to do a single-sided range (e.g. only --max-price 5000)
Verify the order of variables producing the two flags in scripts

Example fix

// before
xianyu search 'mechanical keyboard' --min-price 800 --max-price 300
// after
xianyu search 'mechanical keyboard' --min-price 300 --max-price 800

Defensive patterns

Strategy: validation

Validate before calling

const min = Number(minPrice), max = Number(maxPrice);
if (Number.isFinite(min) && Number.isFinite(max) && min > max) throw new Error(`min-price ${min} > max-price ${max}`);

Type guard

const isSaneRange = (min, max) => min == null || max == null || Number(min) <= Number(max);

Try / catch

try { await xianyuSearch({ 'min-price': min, 'max-price': max }); } catch (e) { if (e instanceof ArgumentError && /greater than max-price/.test(e.message)) { [min, max] = [max, min]; /* swap and retry */ } else throw e; }

Prevention

Sort min/max programmatically before passing them as flags
When deriving bounds from variables, assert order with an invariant check
Omit one bound when you only need a single-sided range

When it happens

Trigger: Running `xianyu search` with --min-price greater than --max-price, e.g. --min-price 5000 --max-price 1000.

Common situations: Swapping flag order mentally ('min 5000 max 1000' when intending a budget of 1000), or computing the bounds from variables where the values were reversed.
