Template format error: Unrecognized resource types: [AWS::Batch::JobQueue, AWS::Batch::ComputeEnvironment, AWS::Batch::JobDefinition]

Question

I'm trying to deploy an AWS Batch service with AWS Fargate, but Cloudformation is returning the following error:

```
Template format error: Unrecognized resource types: [AWS::Batch::JobQueue, AWS::Batch::ComputeEnvironment, AWS::Batch::JobDefinition]
```

I'm using AWS CDK package, and the `"@aws-cdk/aws-batch-alpha": "^2.75.0-alpha.0"` library to do so. Docker image is created successfully, but it seems like the generated Cloudformation template is not being recognized.
The region I'm trying to use is `eu-south-2` (Spain), which supports AWS Batch, so I'm not sure why I'm getting this error.

Answer

Have you taken a look at this re:Post article:
https://repost.aws/knowledge-center/cloudformation-template-validation? Specifically, the section: "Verify the availability of your resource type" would be important.

However, this typically boils down to one of these causes:
- your template has a typo - this could be a spacing issue in YAML, the resource type name has a typo or one of the sub-objects/properties has an issue
- your are trying to access resources not in your region (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-resource-specification.html)
- you are using Serverless resources in your template and the Transform declaration is missing
