[GitHub] [beam] kennknowles opened a new issue, #19283: NPE in BigQuery client library in StreamingBuffer.toPb

[GitBox <gi...@apache.org>]

kennknowles opened a new issue, #19283:
URL: https://github.com/apache/beam/issues/19283

   Sometimes I see the following NPE in my streaming pipeline:
   
    
   
    
   ```
   
   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)
   ```
   
    
   
    
   
   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
