Is there a way to have a fixed fan-in solid proceed despite failed inputs? e.g., if I have solids

a

and

b

that feed into solid

fan_in

, and

b

fails, I'd still like

fan_in

to run with

b

excluded from its input array.

not currently you could sort of approximate it by using an optional output and not yielding it on “failure”, but you would have to try-catch in the solid and it wouldn’t report as a failure, just as no outputs retuned. You could

context.log.error

the error so its in the log but the overview would still show it as green

yeah, we'd talked about wrapping the contents in a try/catch. it's the fact that the solid is still a "success" despite failing which is annoying about that workaround.
