Error running Top transform in Dataflow

When running the following transform in Dataflow (the problem does not happen with the direct running)... I is a streaming pipeline where I am using a SlidingWindow.
```

beam.combiners.Top.Of(n=10, key=lambda item: item[1]).without_defaults() 
```

 
I am getting an error
 
```
