Checklist

[x] I have included information about relevant versions
[x] I have verified that the issue persists when using the master branch of Faust.

Steps to reproduce

start a single Faust worker (python -m opm worker -l info)
wait for worker to report: [^Worker]: Ready
verify that the web-view exposing tables (e.g. http://localhost:6066/object/1480) returns JSON
stop the worker
clear the application state using kafka-streams-application-reset Kafka tool: : kafka-streams-application-reset --application-id opm-v71 --bootstrap-servers 127.0.0.1:9092 --input-topics opm.pmdb.PMObjects,opm.pmdb.PMObjectProperties,opm.pmdb.PMObjectPropertyParams,opm.pmdb.PMPropertyTypes,opm.pmdb.PMPlants
restart the worker
request the same web-view again
Faust worker then raises exception

App code:

kafka_host = 'kafka://localhost'

    kafka_host = os.environ['KAFKA_HOST']

            oid: "No data for the object was found."
        })

Expected behavior

Faust worker webview returns JSON

Actual behavior

Web browser (Firefox) reports 500 Internal Server Error
Faust worker webview raises exception (see traceback below)
Increasing the version in app.py to e.g. 72 resolves the problem - webview returns valid JSON again.
