Use dash in the variable name in yaml

Question

I was trying to run API Gateway locally on my Mac with sam and template.yaml. However, I got this error ValueError: malformed url rule: '/v10/<device-name>' Here is my my code in template.yaml:

  GetListFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: src/lambda/
      Handler: getList.lambda_handler
      Runtime: python3.8
      Events:
        GetList:
          Type: Api
          Properties:
            Path: /v10/{device-name}/
            Method: get

Is there a way to use "-" in the variable name? If not, is there a workaround? Thanks!
