I'm trying to run a Beam pipeline with SQL transforms, parsed with ZetaSQL. I begin with setting options with

`options.setPlannerName("org.apache.beam.sdk.extensions.sql.zetasql.ZetaSQLQueryPlanner");`

When I try creating my SqlTransform with any given query, I get 

```
java.util.ServiceConfigurationError: org.apache.beam.repackaged.sql.com.google.zetasql.ClientChannelProvider: Provider org.apache.beam.repackaged.sql.com.google.zetasql.JniChannelProvider could not be instantiated

```

I've added the following relevant dependencies to my POM in maven:

```
        <dependency>
            <groupId>org.apache.beam</groupId>
            <artifactId>beam-runners-google-cloud-dataflow-java</artifactId>
            <version>2.15.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.beam</groupId>
            <artifactId>beam-sdks-java-extensions-sql</artifactId>
            <version>2.16.0</version>
        </dependency>

```

Is there something else I'm missing here?
