#3608 [BUG] underscore not allowed for node_name in with_overrides Issue created by Nan2018 Describe the bug overriding node_name with a name containing underscore causes failure when registering the workflow Expected behavior node names containing underscore should work Additional context to reproduce

@flytekit.task
def task1(x: int) -> str:
    return str(x)

@flytekit.task
def task2(x: str) -> str:
    return x


@flytekit.workflow
def baby_training_wf() -> str:
    t1 = task1(x=3).with_overrides(node_name='t_1')
    return task2(x=t1).with_overrides(node_name='t_2')

registering the above workflow causes:
