AWS CodeDeploy: STRING_VALUE can not be converted to an Integer

Question

Using AWS CodePipeline and setting a Source, Build and passing `taskdef.json` and `appspec.yaml` as artifacts, the deployment action `Amazon ECS (Blue/Green)` will fail with the error:

STRING_VALUE can not be converted to an Integer

This error does not specify where this error happens and therefore it is not possible to fix.

For reference, the files look like this:

```yaml
# appspec.yaml
version: 0.0
Resources:
  - TargetService:
      Type: AWS::ECS::Service
      Properties:
        TaskDefinition: 
        LoadBalancerInfo:
          ContainerName: "my-project"
          ContainerPort: 3000
```

```json

Any insights on this issue are highly appreciated!

At the "root level" the cpu and memory are and should be strings which you have correct. Issue looking at [ECS Container Def](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-taskdefinition-containerdefinitions.html) memory should be an integer for the container part.

```
       "name": "my-project",
       "memory": "512", << Should be "memory": 512
       "image": "01234567890.dkr.ecr.us-east-1.amazonaws.com/my-project:a09b7d81",
```

Answer

The CodeDeploy agent generates three log files:
* Agent log – Contains information about the agent’s health and overall deployment status.
* Deployment log – Contains STDOUT, STDERR, and information specific to the user-defined scripts that run during a deployment.
* Updater log (Linux agents) – Contains agent updater status.

You can either log into the EC2 instance to view the logs or in the CodeDeploy console, on the event details page for the deployment, choose View logs. This might help to surface some context around the error.
