In my angular app, I use the ng2-file-upload component to upload the file and send to backend as json. ( please correct my if i am wrong )

when i do the post request like:

uploadFile(uploadData:ModelFile):Observable<ModelFile> 

 const formData = new FormData(); //converting to form data

 for(var key in uploadData)
 formData.append(key, uploadData[key]);
 console.log('formData', formData);
 

 const headers = new HttpHeaders( 'Content-Type': 'application/json', 'Access-Control-Allow-Origin':'*' );
 return this.http.post<ModelFile>(environment.baseUrl+`CourseFileUpload`, formData, headers:headers)
 .pipe(
 map(data => 
 return data;
 ),
 catchError(this.handleError)
 )
 

always getting the following error:

"success":false,"successMessage":null,"exceptionObject":null,"returnModel":null,"errorCode":null,"errorMeggage":"Please Enter valid data"

what is wrong here?
here is my template:

<input 
type="file" 
[uploader]="uploader" 
(onFileSelected)="onFileSelected($event)" />

any one help me to sort this issue?
