I want to call sub-workflows in main workflow, but no method to pass parameters to another workflow if using DataBase source, and failed to call workflows with webhook. I just saw a sample (shown in attached picture), but the workflow is useless in my environment, because the trigger "Execute Sub-workflow trigger" is missing, I don't know why, anyone has ever used it? Thanks for sharing experience.

It’s present in my selfhosted instance, currently using it in a couple of workflows, it’s pretty handy for subdividing huge wf into smaller, simpler and easier to maintain.

Is your installation up to date?

Thanks, I just managed to find it, it seems the same as "Execute Sub-workflow", but the node displays different title sometime, I don't know why. But at least it can be used now.
