Description

1) The current camel examples utilize GooglePubsubConnectionFactory  to connect to pubsub till 3.1.0

 

https://github.com/apache/camel/blob/camel-3.1.0/components/camel-google-pubsub/src/main/java/org/apache/camel/component/google/pubsub/GooglePubsubConnectionFactory.java

 

This has been removed from camel 3.2 and above and camel can't connect to pubsub with grpc errors
