So I am working with the general spider in the example dir. I am using the disributed mode as [described in the docs here](https://frontera.readthedocs.io/en/latest/topics/quick-start-distributed.html). Everything seems to start and work ok.  However the spider on encountering the URL triggers the following error. error unpackb() got an unexpected keyword argument 'encoding' As you can see there is some encoding/decoding issue ? I have tried to - reinstall msgpack - re add seeds Working with Ubuntu 18
