This issue has been migrated to https://github.com/apache/beam/issues/19283
> NPE in BigQuery client library in StreamingBuffer.toPb
> ------------------------------------------------------
>
> Key: BEAM-6434
> URL: https://issues.apache.org/jira/browse/BEAM-6434
> Project: Beam
> Issue Type: Bug
> Components: testing
> Affects Versions: 2.9.0
> Reporter: Dan Kruchinin
> Priority: P3
>
> Sometimes I see the following NPE in my streaming pipeline:
>
>
> {code:java}
> Caused by: java.lang.NullPointerException
> com.google.cloud.bigquery.StandardTableDefinition$StreamingBuffer.toPb(StandardTableDefinition.java:106)
>
> com.google.cloud.bigquery.StandardTableDefinition.toPb(StandardTableDefinition.java:230)
> com.google.cloud.bigquery.TableInfo.toPb(TableInfo.java:453)
> com.google.cloud.bigquery.BigQueryImpl.update(BigQueryImpl.java:383)
> com.google.cloud.bigquery.Table.update(Table.java:212)
> com.heysphere.nosegment.dofn.TableRowSchemaMutatorFn.processElement(TableRowSchemaMutatorFn.java:132){code}
>
>
> It happens extremely rarely and I'm not sure what can cause it. To add a bit
> more context, the pipeline performs `Table.update` when it handles failed
> inserts from BigQueryIO and detects that the problem can be fixed by adding
> missing columns (sort of like
> https://github.com/ryanmcdowell/dataflow-dynamic-schema )
>
> Somewhat reminds BEAM-6076
