Jorwoods/type hint flow runs (#950)

* Fix slack once and for all (#946)

The red X keeps coming back so I'd like to mark this as allowably fail-able -- that way the innards of Slack/OAuth/Tableau credentials don't keep polluting test run reports :)

(cherry picked from commit c8170ae)

* Type hint Flow run item

* Continue on error for slack step

* Fix formatting
