Hi, I am not sure if this is related, but AlloyDB is causing some issues for us. We are experiencing this error after upgrading to 5.2.1.

We are only using pubsub and it is fixed by explicit disabling AlloyDB with spring.cloud.gcp.alloydb.enabled=false

---

I wonder, is this a mistake, or do we have an invalid config for only pubsub? Using version 5.2.1. Here is the pom:

    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>spring-cloud-gcp-dependencies</artifactId>
      <version>${spring-cloud-gcp.version}</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
    
     <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>spring-cloud-gcp-starter-pubsub</artifactId>
      <version>${spring-cloud-gcp.version}</version>
    </dependency>
    
   

This is the only "spring.cloud" config in our application properties:

    spring.cloud.gcp.project-id=project-id
    spring.cloud.gcp.pubsub.subscriber.max-ack-extension-period=900

And now, of course: spring.cloud.gcp.alloydb.enabled=false
