[SOLVED] Cannot get parameter value using gojenkins

I am creating an go api using gojenkins library. when I pass parameter in jenkins.BuildJob(ctx,jobName,parameter). I cannot access the parameter. the parameter type is map[string]string

I am providing code snippet.

Jenkin Job create function:

func (l kuberaes) jenkinsJobBuild(i JenkinsBuildReq) ResponseJenkinsResource {
    ctx := context.Background()
    jenkins := gojenkins.CreateJenkins(nil, "http://aescontroller-jenkins.default:8080/", "admin", "pass")
    fmt.Println("Jenkins ", jenkins)
    var deploymentType string
    if i.Deployment == "FRONTEND" {
        deploymentType = "update_frontend"
    } else if i.Deployment == "BACKEND" {
        deploymentType = "update_backend"
    }

During Build job I passed parameter:

func (l kuberaes) jenkinsJobRun(i JenkinsReq) ResponseJenkinsResource {
    ctx := context.Background()
    jenkins := gojenkins.CreateJenkins(nil, "http://aescontroller-jenkins.default:8080/", "admin", "pass")
    // jenkins.DeleteJob(ctx,)


    p := map[string]string{
    "GIT_REPO_P": "https://github.com/aes-sourav/sample-private-1.git",
     }

    p := gojenkins.ParameterDefinition{

    }
    queueid, err := jenkins.BuildJob(ctx, i.JobName, p) // here I passed the params

    if err != nil {
        return ResponseJenkinsResource{
            Message: "Failed to build the job: " + err.Error(),
            Status:  http.StatusInternalServerError,
        }
    }
    build, err := jenkins.GetBuildFromQueueID(ctx, queueid)
    if err != nil {
        panic(err)
    }

    return ResponseJenkinsResource{
        Message: "Successfully run " + build.Job.GetName(),
        Body:    nil,
        Status:  http.StatusOK,
    }
}

Thanks in advance

I have tried : params.GIT_REPO_P it also does not works
