Call a subflow using UUID
Is there an operations in 10.60 that allows me to call a subflow using the UUID, pass that subflows inputs, and return an output field if I know its name?
I'm not sure of the usecase you want here because what you say both in the first request clashes with what you say in your latest post. So let us split down the problem so that maybe we can help you.
You asked if there are any operations that allow you to call a subflow by UUID pass it inputs and return outputs, then you said that you don't want the execution to be in a separate thread (basically you want it to be in the same execution id as the parrent flow). Because of this I have to ask for more clarification. Since a step in a flow can be either an operation or a different flow I assume that the reason of trying to use the flow as a step or subflow in the manner you described is either because you don't have access to the subflow or you want to do a dynamical flow use. Either way we need more info in order to help you.
"you want to do a dynamical flow use"
Exactly. I have a number of different sublfows, each with their own input requirements, but I expect the same return variable. I will process the inputs to know what subflow I want to launch and the inputs it requires. I will process the returned variable value to know if I should continue or do someting else.
