invalid %s: %s

Error message

invalid %s: %s

What it means

A pagination/limit-type integer query parameter failed validation: it must parse as an integer and fall within [1, maxValue] for that parameter. This is a model.BadRequest (HTTP 400) wrapping the param name and offending value.

Solutions

1. Send a positive integer within the allowed range for that parameter
2. Omit the parameter entirely to use the default
3. Check the endpoint docs or helper call site for the specific maxValue

Example fix

// before
?limit=0
// after
?limit=10

v, err := strconv.Atoi(qpValue)
if err != nil || v < 1 || v > int(maxValue) { return fmt.Errorf("%s must be an integer in [1,%d]", qpValue, maxValue) }

func isValidLimit(s string, max int) bool { v, err := strconv.Atoi(s); return err == nil && v >= 1 && v <= max }

When it happens

Trigger: Passing ?limit=0, ?limit=-5, ?limit=abc, or a limit above the max (e.g. >100) to endpoints using this helper (filter suggestions, etc.).

Common situations: Passing 0 meaning 'no limit'; passing an oversized page size; passing a float string like '2.5'.
