Boolean value TypeError in start_example.sh script

[pgasawa]

After setting up a docker container and conda virtual environment (3.6) with the packages as versioned in requirements.txt, I've been attempting to run the start_example.sh script, though am running into the attached error when the script tries to execute this query: SELECT t1._tid_ FROM "hospital" as t1 WHERE t1."Sex"='female' AND t1."Relationship"='husband' .

Changing versions did also not resolve the issue but executing the query directly against the postgres backend (in the docker container) did not result in an error.

Any insights on the issue or how to resolve?
