upload is failing - 500 internal server error

BTW, I have created only aws-s3 instance. No GCP.

Hi Manjuath,

From the logs its evident that the objectstore credentials which are required to configure AmazonWebServiceConfiguration.java class are not able to be injected from the VCAP_SERVICE and so its throwing the error: 2020-06-26T15:54:14.99+0530 [APP/PROC/WEB/0] OUT java.lang.NullPointerException: identity

Could you please verify the service-instance name you would have created in aws landscape.
For instance if the service-instance name is "objectstore-service" the same instance name should be used in the manifest.yaml file as well as in the AmazonWebServiceConfiguration.java class at the given line:
@ConfigurationProperties(prefix = "vcap.services.objectstore-service.credentials")

The same information can also be found in readme in step 2 here.

Thanks

Hi-
Thanks for your reply.
Yes, I have used the same service name.

I have created aws-s3 as instance of objectstore with s3-standard plan.

Same instance name I have used in AmazonWebServiceConfiguration.java

```public BlobStoreContext getBlobStoreContext() {
	return ContextBuilder.newBuilder("aws-s3").credentials(this.getAccessKeyId(), this.getSecretAccessKey())
			.buildView(BlobStoreContext.class);
}```

and also, in yaml file

applications:
- name: objectstore-sample-svc
  host: i302342-objectstore-sample-svc
  memory: 2G
  buildpack: https://github.com/cloudfoundry/java-buildpack.git
  path: target/objectstore-sample-1.0.0.jar
  services:
    - aws-s3

I think Im doing it correctly.

Hi,

As I mentioned in my previous reply the service-instance that you have created as "aws-s3" should match in two places:

1. manifest.yaml (You did it correctly)
2. At @ConfigurationProperties(prefix = "vcap.services.aws-s3.credentials") in AmazonWebServiceConfiguration.java class (Have you changed this as well?)

You've placed the instance name in the below code which is not correct.

public BlobStoreContext getBlobStoreContext() {
	return ContextBuilder.newBuilder("aws-s3").credentials(this.getAccessKeyId(), this.getSecretAccessKey())
			.buildView(BlobStoreContext.class);
}

The job of the above code is to configure aws provider with the objectstore credentials which application automatically injects from VCAP_SERVICES. Please don't change the getBlobStoreContext() method.

Thanks

Yes, thanks for rectifying my mistake. Its working fine now after changing,
from
"vcap.services.objectstore-service.credentials"
to
"vcap.services.aws-s3.credentials"

Thanks for your confirmation.
