builtins.ValueError: Method 'f1' not found in: <amazon_spider 'amazon

 I've a decorator function:

def check_response(f):
    '''decorator for the parse functions. Checks if we're banned or not.'''
    def f1(self, response):
    return f1

 And I use it for parse callbacks:

    def parse_qa(self, response):        

It works ok locally, but emits the following error on ScrapingHub:

Traceback (most recent call last):

I've created a minimal example. So from start_requests returning a list works, while yielding doesn't. In the callback function neither method works.

Again, it's only on ScrapyCloud, locally everything works.
