I am getteing "Value cannot be null.\r\nParameter name: inputParameters" while trying to create a pipeline using the azure devops REST APIs. o

Can anybody suggest what should be the request body parameters for the API Call.

My Implemetation:

Request Body:

{
    "configuration": [
        {

            "folder": "./",
            "name": "trl-pipeline"
        }
    ]
}

as per https://learn.microsoft.com/en-us/rest/api/azure/devops/pipelines/pipelines/create?view=azure-devops-rest-6.0

Response:

    "$id": "1",
    "innerException": null,

            "repository":{
                "id": "{repo id}",
                "type": "azureReposGit",
