The server returned an empty string for GET

Our server is not something we can modify, and seems to return an empty string for a get with a certain EndPoint. Whilst this only shows in the console as an error, an exception is thrown which causes execution to skip through our catch block.

Everything works ok, the backend performs the work and returns as it always does, however I need a better way to handle and parse this error. Any suggestions?

  this.get('ajax').request('/users/restorepassword/' + this.get('username'), {})
    .then(function() {
      _this.set('infoMessage', 'Please check your email!');
      _this.set('errorMessage', '');
    })
    .catch(function(error) {
      // Execution reaches here, everything is ok, the server returns 200 (with an empty string)
      _this.set('infoMessage', '');
      _this.set('errorMessage', error);
    });

@ezekg, I had the same problem and adding dataType: 'text' to post method fixed the error

I’m seeing this issue as well. API is responding with 202 no content but it’s still trying to parse the response as JSON. Having to do this as a workaround:

this.get('ajax')
  .post(`https://api.example.com/foo/bar`, {
    contentType: 'application/json',
    data: JSON.stringify({ data })
  })
  .catch((e) => {
    if (e.message === "Unexpected end of JSON input") {
      return RSVP.resolve()
    } else {
      return RSVP.reject(e)
    }
  })
  .then(() => {
    // …
  })
  .catch((e) => {
    // …
  })
