filtering for integer, but received a non-finite number %v

Error message

filtering for integer, but received a non-finite number %v

What it means

Validation error from floatToInt during int-property filter coercion: the numeric value is NaN or ±Inf, which has no integer representation. floatToInt deliberately rejects these rather than relying on Go's implementation-defined float→int conversion, so the filter is refused instead of silently becoming an arbitrary integer.

// floatToInt safely converts a float64 to int for use as an integer filter
// value. It rejects NaN, ±Inf, values outside the int64 range, and fractional
// values. This allows whole-number floats (e.g. 2.0 or "2.0") to be accepted
// as a convenience, while avoiding Go's implementation-defined behavior for
// out-of-range float→int conversions and silent truncation of fractional
// values.
//
// Note: float64 cannot represent every int64 exactly. Values near the int64
// boundary that ParseFloat rounds up to float64(math.MaxInt64) = 2^63 are
// rejected as out of range. Callers that need exact large integers should
// use the native integer filter value instead of float/text.

Solutions

1. Send a finite integer value
2. Fix client-side computation that produced NaN/Inf
