Creating redshift datasource behaves differently

I tried creating a redshift datasource on two places, one on my local system and one on Domino Data labs.
On my local system I am not able to set an expectation suite against the new datasource and run into this error-
File “/Users/riteshdubey/opt/miniconda3/lib/python3.8/site-packages/great_expectations/render/renderer/”, line 17, in init
self.batch = self.load_batch()
File “/Users/riteshdubey/opt/miniconda3/lib/python3.8/site-packages/great_expectations/render/renderer/”, line 118, in load_batch
batch = self.context.get_batch(self.batch_kwargs, self.suite)

return self._get_batch_v2(

return validator.get_dataset()

self._table = sa.Table(table_name, sa.MetaData(), schema=schema)
AttributeError: ‘NoneType’ object has no attribute ‘Table’
And on Domino data labs there is issue with launching jupyter-notebook so I am not able to do anything.
Can someone help me in either

  1. Troubleshooting the error that I get on my local machine
  2. setting up expectations and changing it without depending on the jupyter notebook

@ridubey Could you please try this again on the latest release? If this still does not work, please report this as a bug in our GitHub issues.
