Run a task despite the previous tasks failure or success in a step function

I have a scenario in step function where I need to execute a task after failure. below is the skeleton of the stepfunction code. but this is currently throwing TypeError for 'FAILED' status alone --> TypeError: (intermediate value).next is not a function? any idea how to execute a following task on failure and post that fail the step function

 const xyzPoller = new Pass(scope, 'Initialize', {
    parameters: {
      status: 'IN_PROGRESS',
      xyzLambdaTimeLimitSeconds: lambdaTimeLimitSeconds,
    },
  })
    .next(disableStreamTask)
    .next(xyzTask)
    .next(
      new Choice(scope, 'Has xyzTask finished?')
        .when(
          Condition.stringEquals('$.status', 'SUCCESS'),
          new Pass(scope, 'xyzTask Finished').next(enableStreamTask),
        )
        .when(
          Condition.stringEquals('$.status', 'FAILED'),
          new Fail(scope, 'xyzTask failed').next(enableStreamTask),
        )
        .otherwise(xyzTask),
    );
