"Query failed: 'NoneType' object is not iterable" Error when starting chat with imported documents

[ibbobud]

After applying the fixes that were provided from a previous Issue that was converted to pull request 163.

Everything is working up to the point that I start a chat on the imported documents, and I get a red error message that says, "Query failed: 'NoneType' object is not iterable" that disappears, and the chat hangs up on "retrieving chunks".

If I look at the logs of the container I see the following. Included some lines above and below for context.
