I got “Response for preflight has invalid HTTP status code 405” error while accessing WCF rest service from ionic 3 angular 5 (latest)

Below is my code  
addNewCategory(sData) {  
return new Promise((resolve, reject) =\>{  
debugger;  
let addCategory: any = {“CategoryId”: sData.categoryId, “CategoryName”: sData.categoryName};  
this.http.post(“[http://avvaikumar-001-site1.1tempurl.com/akgroservice.svc/AddCategory](http://avvaikumar-001-site1.1tempurl.com/akgroservice.svc/AddCategory)”, JSON.stringify({ ‘pCategory’: addCategory }),{  
headers: { ‘Content-Type’: ‘application/json’}  
}).subscribe(result =\> {  
resolve(result);  
}, (err) =\> {  
reject(err);  
console.log(err);  
})  
})  
}

The above URL work well in Chrome post man tool without any issues. Please help me to get out from this error.  
Note: I will reply to your question when I return back to work.  
Thanks
