If the outputs of the nested node are merged in the parent component back into a single flow that leads to a single return node, the single return node can no longer find the start node. If the parent node has multiple Return nodes, even if both are default outputs, it does not fail.
Depending on how the flow is put together, the error will appear
after a significant change (like grouping up the component nodes)
