> I tried different methods to extract table content using *BigQueryIO* but in all scenarios, when I try to use *DataflowRunner* I always get the same *NullPointerException*.
> The reason I found for this error is that while reading the table, *if there are any null values it ignore them without setting the null value*.
> {code}
>         PCollection<TableRow> tableRows = p.apply("ReadFromBQ", 
>         BigQueryIO
>         ._readTableRows_()
>         .from(project:dataset.table)
>         );
> {code}
>  
> The only thing it worked was using DirectRunner with {{.readTableRowsWithSchema()}} but using DataflowRunner I'm still facing the issue.
>  
> Please solve this bug and/or help me to find a solution.
