[aws-dynamodb] when setting PhysicalName.GENERATE_IF_NEEDED to tableName, throwing error `Invalid physical name passed to CloudFormation. Use "this.physicalName" instead`

Hi team, I’m trying to do a cross-env reference on a ddb table. After I specify the tableName to PhysicalName.GENERATE_IF_NEEDED, synthesizing process breaks.

The error message says:

Error: Resolution error: Invalid physical name passed to CloudFormation. Use "this.physicalName" instead.

I suspect this is a bug, as my experiment on a cross-env referenced IAM role works just fine with PhysicalName.GENERATE_IF_NEEDED (not included in the example below)

And I think this error message is confusing. I have no idea what to do with this message. Any context how should I interpret it?

Reproduction Steps

here is an example I used: https://github.com/flyingImer/cdk-mkii

cdk synth breaks even without SomeStack referencing to the ddb table defined in CdkMkiiStack

Error Log

Error: Resolution error: Invalid physical name passed to CloudFormation. Use "this.physicalName" instead.

Yep, I think it’s in the DynamoDB library. I should have a fix out soon.

@isaiahvita are you 100% sure the problem is with this code? Not somewhere else?
