Kenneth Knowles updated BEAM-12835:
-----------------------------------
Description:
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.
