Function formatFormFieldValue

internal/cmdutil/fileupload.go:150–155

formatFormFieldValue renders a JSON-unmarshalled value as a multipart form field string. float64 is handled specially: fmt's default %v/%g switches to scientific notation for values >= ~1e6 (e.g. "1.185356e+06"), which some backends reject when parsing the field as an integer. Use decimal notation i

(v any)

// instead so size / block_num / offset-style numeric fields round-trip cleanly.
// All other types fall through to %v.
func formatFormFieldValue(v any) string {
	if n, ok := v.(float64); ok {
		return strconv.FormatFloat(n, 'f', -1, 64)
	}
	return fmt.Sprintf("%v", v)
}
