Angular2 RC5: get json data from web service not working

I am trying to load data from data service but ID appears as type error

selectedModule(item: any) {
  this.module = item;
    console.log(this.module);
    this.dataService.getAny('/modules/get-by-module', "Id", '1')
        .then((module: IModuleBySector) => {
            const cust = JSON.stringify(module);
            this.moduleSelected = module;
            console.log(this.moduleSelected);
    });
 }

I believe you want to send ID to the server side code and want to get data whose ID=1. You should try this,

selectedModule(item: any) {
  this.module = item;
    console.log(this.module);
    this.dataService.getAny('/modules/get-by-module?Id=1')
        .then((module: IModuleBySector) => {
            const cust = JSON.stringify(module);
            this.moduleSelected = module;
            console.log(this.moduleSelected);
    });
 }
