CWE: CWE-476 \u2014 NULL Pointer Dereference
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.

Code:
  def testTensorArrayConcatFailsWhenMissingStepContainer(self):
    @def_function.function
    def func():
      y = data_flow_ops.TensorArrayConcatV2(
          handle=["a", "b"],
          flow_in=0.1,
          dtype=dtypes.int32,
          element_shape_except0=1,
      )
      return y

    with self.assertRaisesRegex(
        errors.NotFoundError, "Container .* does not exist"
    ):
      self.evaluate(func())
