> URL: https://issues.apache.org/jira/browse/BEAM-8029
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.14.0
> Reporter: Chris Larsen

> Code to read from BigQuery that is causing the issue:
> {code:java}
> pipeline
> .apply(BigQueryIO
> .read(SchemaAndRecord::getRecord)
> .from(options.getTableRef())
> .withMethod(Method.DIRECT_READ)
> .withCoder(AvroCoder.of(schema)))
> {code}
> If we remove .withMethod(Method.DIRECT_READ) then there is no issue.
>
> The error is:
> {code:java}
