Referencing existing output values from other CloudFormation stacks

[nathanagez]

Describe the bug
When trying to reference an output value from other Amplify-managed category CloudFormation stack the output value seems to not be shared to amplify-video stack.

To Reproduce
In backend-config.json search amplify-video key and add the dependsOn property, i.e.:

"video": {
    "projectName": {
      "service": "video",
      "serviceType": "video-on-demand",
      "providerPlugin": "awscloudformation",
      "dependsOn": [
        {
          "category": "api",
          "resourceName": "projectName",
          "attributes": [
            "GraphQLAPIIdOutput",
            "GraphQLAPIEndpointOutput"
          ]
        }
      ]
    }
  }

Configure CloudFormation stacks like they do inside documentation.
When you'll try to access attributes inside CloudFormation stack the following error will appears:

Parameters: [apiprojectNameGraphQLAPIEndpointOutput, apiprojectNameGraphQLAPIIdOutput] do not exist in the template

Expected behavior
Share output values correctly to amplify-video CloudFormation stacks

amplify -v
5.1.0

amplify video -v

Seems similar to an issue I opened a while ago.

This would be really useful!

@wizage any ideas if this is in scope for implementation anytime soon?

[danielvouch]

Is there any update to this feature by any chance?

I'd love to be able to access lambda layers + DB tables in a video trigger.
