----------------------------------------

             Summary: BigQueryIO.readTableRows() throws NullPointerException
                 Key: BEAM-12835
                 URL: https://issues.apache.org/jira/browse/BEAM-12835
             Project: Beam
          Issue Type: Bug
          Components: io-go-gcp
    Affects Versions: 2.32.0, 2.31.0
            Reporter: Francesco Galiano


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*.

        PCollection<TableRow> tableRows = p.apply("ReadFromBQ", 

        BigQueryIO

        ._readTableRows_()

        .from(project:dataset.table)

        );

 

The only thing it worked was using DirectRunner with ._readTableRowsWithSchema_() but using DataflowRunner I still facing the issue.

 

Please solve this bug and/or help me to find a solution.
