Hi,  
Is there a reason why it’s not working when I query a spacy NER model with a list of inputs ?

I’m able to send multiple inputs at once with other types of model, but in this case the only way to make it work is with a single string input.  
Otherwise the api is returning this {‘error’: ['str type expected: ` __root__ ` in `parameters`']}.

Thanks !
