AWS Step Function: ignore input from previous state, and use "Parameters" as input

Question

So I have a state defined as below.

    "process-abc": {
      "Type": "Task",
      "Resource": "arn:aws:lambda:us-east-1:my-lambda...",
      "Parameters": {
        "type": "my-type",
      },

However, when I run step function, I don't see the "type": "my-type", in the state input, I only see the input as something from the previous state output.

How can I only pass "type": "my-type" as the only input into the current state?

If you did not define any result path, by default input to the next state is the output of the previous state.

See https://docs.aws.amazon.com/step-functions/latest/dg/input-output-resultpath.html

You can set the result path of the state 1 to null to ignore the state 1 result and pass the state 1 input to the state 2.
