        "sinusoid": -0.978147601,
        "a": {
            "sinusoid": "2.0"
        }
    },
    "asset": "sinusoid",
    "id": "a1bedea3-8d80-47e8-b256-63370ccfce5b",

}
  1. To replace an asset apply a configuration would be as follows

  • Operation : asset

  • Find : sinusoid

  • Replace With : sin

Output

        "a": {
            "sinusoid": 2.0
        }
    },
    "asset": "sin",
    "id": "a1bedea3-8d80-47e8-b256-63370ccfce5b",
