Workflow Validation Error with Invoke a workflow action

Question

I'm using the 'Invoke a work in this workflow app' action in my workflow, so that I can kick off another logic app.

When I try to set the name of the workflow to invoke in the 'workflow name' parameter using a variable like so:

I get the following error when saving:

The only thing that seems to work is using the in built drop down option however I need to be able to set it from a variable which is retrieved from a previous action dynamically and it can change.

Is this a known bug or am I missing something here?

@Peter AFAIK the validation is the same as you enter the workflow name while we create a new workflow. So the workflow name doesn't support the character such as '@', single quotes, braces, etc.

In the code view, it creates the below code and id parameter cannot have unsupported character as we can see @variables(test)

"Invoke_a_workflow_in_this_workflow_app": {  
                "inputs": {  
                    "host": {  
                        "workflow": {  
                            "id": "@variables('test')"  
                        }  
                    }  
                },  
                "runAfter": {  
                    "Initialize_variable": [  
                        "Succeeded"  
                    ]  
                },  
                "type": "Workflow"  
            }  

I have reached out to my team to confirm my understanding and I will keep you posted.

Update 10/26:
I have got confirmation from my product team that dynamically determining the workflow name is not supported. In case if you have HTTP workflow you can call your HTTP trigger workflow using HTTP connector.
