> Key: BEAM-12835
> URL: https://issues.apache.org/jira/browse/BEAM-12835
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.31.0, 2.32.0
> Reporter: Francesco Galiano
> Priority: P2
> Labels: stale-P2
>
> 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.
