not sure, how Union work in this case, you should check the module code

```Union typing is only needed when you have a statically typed language, as you need to declare that an object can return one of multiple types (in your case an int or str, or in the other example str or NoneType)```

<@U04HSHJN1HN> we use python 3.9.16 for our deploys with pulumi.
Here is the sdk code:
<https://github.com/pulumi/pulumi-aws-native/blob/v0.54.0/sdk/python/pulumi_aws_native/dynamodb/table.py#L19>

<https://github.com/pulumi/pulumi/blob/v3.59.0/sdk/python/lib/pulumi/runtime/rpc.py#L150>
Probably the issue is with defining the key_schema with only the hashkey and not the rangekey in the list.
