Spring Cloud Config Cloud Config Server (w/GCP Secret Manager) Throws ClassNotFoundException

I have a very vanilla setup of Spring Cloud Config Server. Git functionality works great. Wanting to connect it to GCP Secret Manager. Problem 1 is the documentation is lacking and I haven't been able to find many resources online so AI is not very good at it either, but it is really all I have been able to work with.

Main issue is I finally get it to run but it throws an error on start

I'm using what I believe to be compatible versions: Spring Boot 3.4.7 Spring Cloud 2024.0.1 Spring Cloud GCP 6.2.2

With the following core dependencies in the build.gradle

    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-actuator'

    implementation 'org.springframework.cloud:spring-cloud-config-server'
    implementation 'com.google.cloud:spring-cloud-gcp-starter-secretmanager'

application.yaml

server:
  port: 8888
spring:
  cloud:
    config:
      server:
        gcp-secret-manager:
          order: 1
          token-mandatory: false
    gcp:
      project-id: my-project-id
      secretmanager:
        enabled: true
        allow-default-secret: true
  application:
    name: config-server
  profiles:
    active: secret-manager

I'm running it locally for the time being. It is using my Google Application Credentials file which I have full access to the project and can access all secrets via gcloud. As best I can tell I've included the correct gradle dependencies but class not found would imply I'm missing something. Is this an issue or is the configuration incorrect.
