Vaex-server "TypeError: unhashable type: 'KeysView'" #1392

I am trying to start my own vaex server my dataset is a partitioned parquet file having the hive format: partitioned country==Africa
week==9
uuid.parquet
week==10
uuid.parquet
..... 
  country==India
  |          |
  |          week==9
  |          |      | 
  |          |       uuid.parquet
  |          week==10
  |          |       |
  |          |       uuid.parquet
  |          | ..... 
  |......

I am trying to run the server from the same folder where my partitioned parquet file "partitioned" is located using the command: $ vaex webserver ./partitioned

this gives me an error saying: $ vaex webserver ./partitioned

Note: Getting the same error when reading a .csv file or a .parquet file (non-partitioned).

That should be fixed with a new release, let us know!
