Error while uploading a file with Angular ng file upload

Question

I have an issue with ploading a file to my server. I follow the structure provided in the demos:

file.upload = this.Upload.upload({
          url: "/api/license/upload",
          method: "POST",
                 data: {
                     name:file.name
                 },
                 file: file
          }).then(function (resp:any) {
               console.log('Success ' + resp.config.data.file.name + 'uploaded. Response: ' + resp.data);
            }, function (resp:any) {
                 console.log('Error status: ' + resp.status);
            }, function (evt:any) {
                var progressPercentage = parseInt(evt.loaded / evt.total);
                 console.log('progress: ' + progressPercentage + '% ' + evt.config.data.file.name);
          });
 }

However, when I am trying to upload a file, in a response from a server I get 200 (which is OK), but then the app crashes with the following:

SyntaxError: Unexpected token Y

    at n.$digest (http://localhost:4000/dist/vendor.min.js:135:233)

Any ideas on what might be the problem?

Alright, I found out what was the issue: the response from the server was in a form of string, not a JSON.
