Issue on vaex.dataframe.DataFrame.unique

In the API document of vaex.dataframe.DataFrame.unique, it is written: can use expression or list of expressions:

But when I used the expression list, the program encountered an error prompt:

ValueError: ['decimalLatitude', 'decimalLongitude'] is not of string or Expression type, but <class 'list'>

This means that I cannot use a list as input, and I think this may be a bug
