serverless: DeploymentBucket parameters not being replaced

I’ve noticed that when I try and do parameter replacement for the provider.deploymentBucket or provider.deploymentBucket.name property I am getting errors.
I receive these error with and without the serverless-psuedo-parameters plugin. Configuration: (Same error when nesting name or omitting it or using Fn::Sub)

  deploymentBucket: 
    name: !Sub 'development-team-deployment-bucket-${AWS::AccountId}'

Result: Configuration warning at 'provider.deploymentBucket.name': should be string

Configuration:

  deploymentBucket: ${self:provider.stage}-brandzooka-deployment-bucket-#{AWS::AccountId}

Result: Configuration warning at 'provider.deploymentBucket': should match pattern "(?!^(\d{1,3}\.){3}\d{1,3}$)(^(([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9])\.)*([a-z0-9]|[a-z0-9][a-z0-9-]*[a-z0-9])$)"

Configuration Where ${self:custom.accountId} = ${AWS::AccountId}

  deploymentBucket: 
    name: !Sub ${self:provider.stage}-brandzooka-deployment-bucket-${self:custom.accountId}

Result This is what wound up in the .serverless/serverless-state.json file which looks like it should work BUT I get a fatal error from serverless Could not locate deployment bucket. Error: str.indexOf is not a function

      "deploymentBucket": {
        "Fn::Sub": "development-brandzooka-deployment-bucket-${AWS::AccountId}"
      },

However this works, so I believe the issue lies in the recent integration of serverless pseudo parameters.

${self:provider.stage}-brandzooka-deployment-bucket-413466xxxxxx
