Can't use stable diffusion executor

[tom-doerr]

I'm trying to use the stable diffusion executor using

doc = Document(text=prompt).post(server_url, target_executor='stable')
print(doc)
da = doc.matches

but I'm getting no images back:

<Document ('id', 'text') at 6f0eb3ec81132016722bd729f8b88e25>

---------------------------------------------------------------------------

    436         if not self:

    438 
    439         import matplotlib.pyplot as plt

ValueError: <DocumentArray (length=0) at 140421956184400> is empty

Is the stable diffusion executor not online?

Hi @tom-doerr. Yes, we haven't deployed stable diffusion executor to our demo server yet.
