cannot interpret %q value as int16

Error message

cannot interpret %q value as int16

What it means

The target field is int16; strconv.ParseInt(s,10,16) failed, meaning the value is not an integer or exceeds the int16 range (-32768..32767).

Solutions

1. Use a value within int16 range (-32768..32767).
2. Verify the field type; ports above 32767 belong in int/int32 fields.
3. Pre-validate with strconv.ParseInt(v,10,16) before calling.

Example fix

// before
SetString(&c, "spec.someInt16Field", "40000") // overflows int16
// after
SetString(&c, "spec.someInt16Field", "32000")

if _, err := strconv.ParseInt(val, 10, 16); err != nil {
    return fmt.Errorf("value %q does not fit int16", val)
}

func isInt16(s string) bool {
    _, err := strconv.ParseInt(s, 10, 16)
    return err == nil
}

if err := SetString(&obj, path, val); err != nil {
    if strings.Contains(err.Error(), "as int16") {
        return fmt.Errorf("%q must be an integer in [-32768, 32767]", val)
    }
    return err
}

When it happens

Trigger: SetString(&obj, "spec.port16", "70000") or any non-numeric string on an int16 field.

Common situations: Port or small-range numeric fields (e.g. node port ranges) given out-of-range values like 65535+ in `kops set cluster` commands.
