Description

Integration testing exposed a bug in cases where values_data.len() is zero. This fails with divide by zero error.

// check that values_data length is multiple of len
assert!(
    values_data.len() / len == self.list_len as usize,
    "Values of FixedSizeList must have equal lengths, values have length {} and list has {}",
    values_data.len(),
    len
);
