> Reporter: Artur Denysenko
> Labels: bug

> I work with UUID 16 bytes columns:
> ```sql
> CREATE TABLE IF NOT EXISTS log (
> id BINARY(16) NOT NULL PRIMARY KEY,
> c BINARY(16) NOT NULL,
> t BINARY(16) NOT NULL
> e VARCHAR(255) NOT NULL)
> IMMUTABLE_ROWS=true;
> CREATE INDEX IF NOT EXISTS log_idx_t ON log(t);
> CREATE INDEX IF NOT EXISTS log_idx_c ON log(c);
> ```
> I have this exception:
> ```
> java.lang.NullPointerException

> And it happens then we try to use null [indexColumnType] resulted from
> [IndexUtil.getIndexColumnDataType(isNullable=true, dataColumnType="BYTE")]
> ```java
> boolean isNullable = true;
> ...
> if (dataPkPosition[i] == -1) {
> dataColumnType = indexedColumnTypes.get(j);
> ImmutableBytesPtr value = valueGetter.getLatestValue(iterator.next());
> if (value == null) {
> ptr.set(ByteUtil.EMPTY_BYTE_ARRAY);
> } else {
> ptr.set(value.copyBytesIfNecessary());
> }
> j++;
> } else {
> // does not execute in our case
> }
> PDataType indexColumnType = IndexUtil.getIndexColumnDataType(isNullable,
> dataColumnType);
> ```
