AI agent HTTP request fails when passing a parameter

Hi,

I'm attempting to call an API using an AI agent and an HTTP request. I'm providing an object ID as an input parameter and consistently receiving an "Invalid URL" error.

    {
      "parameters": {
        "toolDescription": "get metadata for business object by id",
        "url": "  https://testdl-schema/v1/schema-creation-currated/{boId }",
        "sendHeaders": true,
        "parametersHeaders": {
          "values": [
            {
              "name": "cookie",
              "valueProvider": "fieldValue",
              "value": ""
            }
          ]
        },
        "placeholderDefinitions": {
          "values": [
            {
              "name": "boId",
              "description": "=the id of the first business object / bussiness_object from the list {{ $json.output.business_object[0].id }}"
            }
          ]
        },
        "optimizeResponse": true
      },
      "type": "@callin.io/callin.io-nodes-langchain.toolHttpRequest",
      "typeVersion": 1.1,
      "position": [
        520,
        100
      ],
      "id": "49a062f4-771e-4181-bc4d-368036583b92",
      "name": "get metadata",
      "notesInFlow": false
    },

I've observed from the debug output that the parameter is being correctly passed to the node:

However, I'm still encountering the error "There was an error: "Invalid URL"".

I'm unable to locate where to view the exact request that callin.io has made.
