This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.
Go to Suggested ReplacementVariable Condition Loop EndIn combination with a Generic Loop Start node, this node lets you execute the body of the loop until a certain condition on one of the flow variables is met. In the dialog you can choose one of the available flow variables and which condition should cause the loop to finish.
