> {code}
> *Cause*
> This is caused by a Guava dependency conflict:
> - Kinesis Consumer > {{18.0}}
> - GCP PubSub > {{26.0-android}}
> {{NettyChannelBuilder}} fails to initialise due to missing method in guava:
> - {{com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;CLjava/lang/Object;)V}}
> *Possible Fixes*
> - Align Guava versions
> - Shade Guava in either connector
