Anyone,

I infrequently get the below error when running scripts via numerapi. I can see no logical reason why this error occurs, code seems good.

Thank you in advance.

/lib/python3.6/site-packages/numerapi/base\_api.py", line 121, in raw\_query  
raise ValueError(err)  
ValueError: Your session is invalid or has expired.
