Internal Server Error, AttributeError: 'Query' object has no attribute 'keys'; Version 8.0.0.b32245

We are experiencing query failures and data source connection issues while we didn’t make any change on our side.

A summary of the issue and the browser/OS environment in which it occurs.

Technical details:

From our log, it seems that redash is having trouble recognizing data sources connections, and the error almost looks like a bug from the code. However, it has been working fine since yesterday. I have attached the log below. The consequence of it is we can not run any query at the moment since there is no connected data source at all.

Any help is greatly appreciated !!
