Tasklist authentication issue with 8.5.0 version

Hi,

I’m using below code in springboot application to authenticate zeebe and tasklist.


//zeebe authentication
return new ZeebeClientCloudBuilderImpl()
				.withClusterId(credentials.getClusterId())
				.withClientId(credentials.getClientId())
				.withClientSecret(credentials.getClientSecret())
				.withRegion(credentials.getRegion())
				.build();

//tasklist authentication
JwtConfig jwtConfig = new JwtConfig();
		jwtConfig.addProduct(Product.TASKLIST, new JwtCredential(credentials.getClientId(), credentials.getClientSecret(), "tasklist.camunda.io", "https://login.cloud.camunda.io/oauth/token"));

		Authentication auth = SaaSAuthentication.builder()
				.withJwtConfig(jwtConfig).build();
		return CamundaTaskListClient.builder().shouldReturnVariables()
				.taskListUrl(
							"https://" + credentials.getRegion() + ".tasklist.camunda.io/" + credentials.getClusterId())
				.authentication(auth).build();

Zeebe authentication is working fine and I’m able to start the process as well.

But when I’m using tasklist I’m getting this error
Authenticating for TASKLIST failed due to java.lang.NullPointerException: Cannot invoke “io.camunda.common.json.JsonMapper.toJson(Object)” because “this.jsonMapper” is null

Below is the dependency I’m using.
```

    <dependency>
        <groupId>io.camunda</groupId>
        <artifactId>camunda-tasklist-client-java</artifactId>
        <version>8.5.0</version>
    </dependency>
      
     <dependency>
        <groupId>io.camunda</groupId>
        <artifactId>zeebe-client-java</artifactId>
        <version>8.5.0</version>
    </dependency>

Thanks you for the help
