Use Case

Typescript 4.4 (beta) forces you to narrow the type of an error in a catch block. We should locally upgrade to the beta and fix the errors it reveals. It would make error handling more accurate.

Dependencies

• none

Unknowns

We're doing a lot of catching sync errors and turning them into async errors by passing them into callbacks. It's not clear if this is correct behavior and/or expands the scope of this ticket.

Acceptance Criteria

Implementation Requirements

• Fix TS errors revealed by ts 4.4

Testing Requirements

• none, unless narrowing logic is complex? But we shouldn't get there.

Documentation Requirements

• none

Follow Up Requirements

• If other significant TS errors crop up, file a ticket for them.
