nodes_ is a pybind11::set, which is not subscriptable. nodes_[0] compiles because object_api::operator[] accepts a py::handle and the literal 0 converts to a null handle, so pybind builds py::str(nullptr) and the process dies in strlen(). The line only runs when a task raises and exactly one node is registered, which is why normal use never reaches it. Take the element through py::list(nodes_), as the file already does when iterating nodes_ elsewhere. Three tests in test_executor.py were excluded from EventsExecutor because of this crash; re-enable them. Signed-off-by: Puja <catplotlib@gmail.com>
