> When using PubsubAvroToBigQuery Dataflow template, [I noticed this issue.
> |https://github.com/GoogleCloudPlatform/DataflowTemplates/issues/287]
> This seems to be related to the way
> [toBeamRow|https://github.com/apache/beam/blob/v2.32.0/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryUtils.java#L593]
> is handling TableRow with List containing null values.
> The error trace has this path (I only added the relevant ones):

> On c., a validation of null "bqValue" objects is performed; however, it
> appears that some of the elements are of List type (for BigQuery Record
> type); therefore, the List object is validated to be non-null, but not the
> elements of the List.
> On d., the method is executed recursively to process all the elements of the
> List object; however, it seems that some objects are Null so this method is
> throwing the NullPointerExceptions.
> *toBeamValue method should probably not used toBeamValue recursively but
> toBeamRowFieldValue instead.*
