sqlalchemy InvalidRequestError

After the initial installation, uploading my dataset and creating a datarun, upon hitting Run, I get the following errors in my console:

I'm facing a similar sqlalchemy error but for class Datarun, following the exact same steps described by @xorb0ss :

Still facing the same error after Merge pull request #23 , which fixed some of the scripts ...
