AWS SAM with !ImportValue and !Ref cannot use together

I have a Lambda function to deploy using AWS SAM. In some way, I cannot build stack if I set up layers using `!ImportValue` and `!Ref` together. If I comment one of them, it builds without errors.

```
Parameters:
LoggingLayerARN:
Type: AWS::SSM::Parameter::Value
Default: /some/parameter

TestLambda:
Type: AWS::Serverless::Function
Properties:
Layers:
- !ImportValue AnotherStackLayer
- !Ref SSMParameterLayerARN
```

The error I've got:

`Layer References need to be of type 'AWS::Serverless::LayerVersion' or 'AWS::Lambda::LayerVersion'`
