Ok,I will read more carefully the documentation then 😉

[lovis]

Just ctrl+space the hell out of the ide 😅

[fstn]

One more question 😞

val type: BotFlowNodeLinkType = BotFlowNodeLinkType.get(
                    it.camundaInputParameters
                            .filter { param -> param.getAttributeValue("name") == "btn_type" }
                            .map { it.textContent }
                            .firstOrNull()
                            ?: throw  MissingBtnTypeException(it.camundaInputParameters))
                    ?: throw  MissingBtnTypeException(it.camundaInputParameters)

[fstn]

I would like to throw an exception if firstOrNull return null

[fstn]

but I need to put it 2 times otherwises, I need to put BotFlowNodLinkType?

[fstn]

the other solution is to put !! at the end

[lovis]

just use first instead of firstOrNull ?

[edwardwongtl]

Because firstOfNull returns Type? instead of Type, @lovis’s answer should be most appropriate

[lovis]

Also, first(predicate) will throw if not found

[fstn]

If I try to use first, I got an emptyList exception 😞

[lovis]

maybe you could change BotFlowNodeLinkType.get() then, that it accepts null? Then you only have to throw once

[fstn]

Yes it seems to be the best solution
