The [index] part doesn’t seem to work in Dynamo 18.104.22.16886 as it returns a null.
The same script did work in Dynamo 22.214.171.12460 and returned the value at the index.
Is this something that needs fixing? I’d like that because I have scripts written in 2.5 that don’t work properly now. I can fix it with a workaround for now but it’s not fun.
