Intermittent ValueError with quandl.fred_gnp

I'm encountering the following error while working with fred_gnp from quantopian.pipeline.data.quandl

ValueError: Bad response: Pre-processing failed with:  
Failed to decode data access token.  

fred_gnp which has suddenly stopped working usingPipeline. To avoid attaching the entire notebook, the following code raises the error locally.

from quantopian.pipeline.filters import StaticAssets  
from quantopian.pipeline import Pipeline, CustomFactor  
from quantopian.research import run_pipeline  
from quantopian.pipeline.data.quandl import fred_gnp

class LatestMacroEconomic(CustomFactor):  
    window_length = 1  
    def compute(self, today, asset_ids, out, values):  
        out[:] = values[-1]  


pipe = Pipeline(  
    columns={  
        'fred_gnp': LatestMacroEconomic(inputs=[fred_gnp.value])},  
    screen=StaticAssets([symbols('AAPL')])  
)

df = run_pipeline(pipe, '2017-01-01', '2017-12-01')

@ Joseph Are you still having issues with the fred_gnp dataset? I tried the code above in a notebook and it works without an error. There were some previous data upload issues which may have caused the error you experienced. Sorry for any inconvenience.
