Question

Hello,

I have a Greengrass environment deployed on a Linux machine with the following deployment:

| Component | Version |
| --- | --- |
| aws.greengrass.Cli | 2.9.3 |
| aws.greengrass.Nucleus | 2.9.3 |
| aws.greengrass.SecretManager | 2.1.4 |
| aws.greengrass.StreamManager | 2.1.2 |
| aws.greengrass.SystemsManagerAgent | 1.0.0 |
| aws.iot.SiteWiseEdgeCollectorOpcua | 2.2.0 |

This deployment is green and works fine, but when I add the SiteWise Edge Processor and Publisher with following version:

| Component | Version |
| --- | --- |
| aws.iot.SiteWiseEdgeProcessor | 2.1.29 |
| aws.iot.SiteWiseEdgePublisher | 2.3.1 |

I receive the following error:

```
2023-02-22T11:39:26.251Z [INFO] (Copier) aws.iot.SiteWiseEdgeProcessor: stdout. [2023-02-22] [11:39:26] ERROR - Error while downloading file s3://sitewise-edge-component-artifacts-eu-central-1/dynamodb-local/1.1.0/dynamodb_local_latest.zip. Error: Download failed for /greengrass/v2/work/aws.iot.SiteWiseEdgeProcessor/dynamodb_local_latest.zip: (verification: FAILED):. {scriptName=services.aws.iot.SiteWiseEdgeProcessor.lifecycle.Install.Script, serviceName=aws.iot.SiteWiseEdgeProcessor, currentState=NEW}
```

Looks like there is an issue installing that file, but I verified the file exists on that bucket and Greengrass has the right to access it from the IAM Role.

Do you know what is the issue about?

Many thanks in advance!

Answer

As you are installing SiteWise Edge Gateway with Data processing pack, we highly recommend that you do the entire deployment through the console following steps outlined here using Default setup: https://docs.aws.amazon.com/iot-sitewise/latest/userguide/create-gateway-ggv2.html

Console will create all the required permissions in the cloud, and the installation script will setup your OS and install missing dependencies.
In advanced setup there are a number of steps that you will need to perform manually, like installing Java and creating correct IAM policy which is attached to the gateway. Your current setup is missing correct IAM policy assigned to the Greengrass Core. The policy can be found here at the bottom of the page: https://docs.aws.amazon.com/iot-sitewise/latest/userguide/configure-gateway-ggv2.html
