Limitations on Step Functions SDK Integration for Elasticsearch

Question

After "Announcement: AWS Step Functions adds support for over 200 AWS Services with AWS SDK Integration":    
   
We wanted to use the new AWS SDK Integration in Step Functions to start up a OpenSearch/Elasticsearch Domain, however Step Functions does not seem to support the **EBSOptions** parameter , as it errors with:  
  
The Parameters '{\"ElasticsearchClusterConfig\":{\"InstanceType\":\"t3.small.elasticsearch\",\"InstanceCount\":1,\"DedicatedMasterEnabled\":false,\"ZoneAwarenessEnabled\":false},\"DomainName\":\"test-12345\",\"ElasticsearchVersion\":\"7.1\",\"EBSOptions\":{\"EBSEnabled\":true,\"VolumeType\":\"gp2\",\"VolumeSize\":100},\"VPCOptions\":OMITTED,\"AccessPolicies\":OMITTED}' could not be used to start the Task: The field \"EBSOptions\" is not supported by Step Functions  
  
The same parameters work just fine using boto3.  
  
Is this by design? Should we expect support in the future or it is never going to be an option? Is there any documentation about these limitations?  
  
Is there a workaround other than using the SDK directly in a Lambda?

Hi  
The parameters are Pascal case so instead you can use EbsOptions and it should work.  
Thanks

Answer

That works (I had to do the same with **VPCOptions** and other fields)  
  
A similar issue that came up though is on the **Tags** field though on the same ElasticSearch creation:  
_The field "Tags" is not supported by Step Functions_  
  
Any idea on how to fix this one?
