string[] publishTargets = new string[] { "tcm:0-1109-1" };

This is the problem in your code. Id you are sending is definitely TcmId of publication, not publication target. TcmId of Publication Target ends up with 65537, so TcmId looks like this: tcm:0-XXX-65537.

This is the issue you observe when you try to send ID of Publication instead of Publishing target. To get Id of the target, check id in Administration tab: enter image description here

Marko is correct about the error and what is causing it, but you can only check for the Publication Target the way he describes if you are on version 2013 SP1 at the latest, or a greater version if you have legacy publishing enabled.

If you are on Web 8 and up, you can also publish to:

  • Purpose, which is a string value. To see which Purposes you have open the relevant BPT in your Publication
  • Target Type. To get the ID of the Target Type, open the publish dialog and hover on the Target's name.

Both approaches are illustrated below:
