How to avoid NoSuchElementException in `catchTag`

Playground example: https://effect.website/play/#001b2967155e

Right now when I return an

Option.none()

Option.none()

from a

catchTag

catchTag

handler, Effect (seems to) automatically add a

NoSuchElementException

NoSuchElementException

to the list of Effect errors. But in this case I want to return an Option from the API.

I've tried transforming the result using

Effect.either

Effect.either

and such but I just can't seem to figure out how to not have

NoSuchElementException

NoSuchElementException

show up.

Is there a different API than

catchTag

catchTag

which acts more like

Effect.map

Effect.map

rather than

Effect.andThen

Effect.andThen
