Hey.  
I´m building a custom CMS to our discourse platform.  
I’m having some trouble when trying to post something.  
I’m building it in angular and the programing language is typescript.  
Here is a picture of my function

```plaintext
 createACompetition(CompetitionName: string, groupName) {
    const headers = new HttpHeaders().set('Content-Type', 'multipart/form-data');
    const data = new FormData();
    data.append('api_key', WLIApiKey);
    data.append('api_username', WLIUsername);
    data.append('color', '49d9e9');
    data.append('text_color', 'f0fcfd');
    data.append('name', CompetitionName);
    console.log(data.get('name'));
    // Security group on create
    // data.append('permissions[]' + groupName, '1');

    return this.http.post(url + '/categories', data, {
      headers
    });
  }

```

and this is my error message

Did I make a mistake in my post request ?

My guess is that the API key is wrong or the user didn’t have permission.

No, that not the problem.  
I Think it has something to do with headers?
