TypeError: EventSourceArn.split is not a function

Serverless Framework

Hello,

We are trying to upgrade from serverless v2 to v3, in v2 we used erverless-pseudo-parameters plugin to resolve AWS vars, while I read that in v3 these are supported out of the box but they are throwing the same error.

resorted to using join and sub but its not able to resolver the vars, here’s a snippet which is throwing TypeError, this resource has been created out of this stack, so trying to set this event stream as a trigger for lambda. It feels like we are overlooking something small here, appreciate on any pointers on this

    events:
      - stream:
          arn: !Join [ "-" ,[ !Sub "arn:aws:kinesis:${AWS::Region}:${AWS::AccountId}:stream/portal" , "${self:provider.stage}" ] ]
          batchSize: 1
          maximumRetryAttempts: 10
          startingPosition: LATEST

Error:

Environment: linux, node 14.21.3, framework 3.28.1 (local), plugin 6.2.3, SDK 4.3.2
Credentials: Local, environment variables
