AttributeError: 'NoneType' object has no attribute 'predict'

To author:
When we do the inference, the system would have the following error,

File "inference.py", line 149, in ask
top_k_reader=request.top_k_reader, filters=request.filters,
File "/workspace/haystack/haystack/finder.py", line 57, in get_answers
results = self.reader.predict(question=question,
AttributeError: 'NoneType' object has no attribute 'predict'

Do you have any idea? Thank you

Hi @laifuchicago, it seems from the error message that the Finder in the API doesn't have a reader instance. Let's narrow down the issue together. Can you provide the following details:

• how is the FINDERS variable initialized in inference.py? If possible, could you share your complete inference.py file?
• what commit of Haystack you're working with?
• are you using the doc-qa orfaq-qa endpoint?

Now, we have solved this problem, thanks.
But the new problem is when we use faq-qa, it would show 500 Internal server error, but it's ok with doc-qa, do you have any idea?
