Unable to select a topic for Amazon Transcoder

I want to have my Amazon Transcoder post a notification to a SNS topic when some events happen, but unfortunately I'm getting an error message when I try to select the existing topic from the "Edit Pipeline" page: "Role ARN is invalid: does not start with arn"

I'm not sure what I'm doing wrong, apparently it seems pretty straightforward. Here's the steps I've done:

  1. Selected my Pipeline
  2. Click "Edit"
  3. Went to "Notifications" sections and created a new topic right there (here I would expect it to have auto selected after the creation but apparently it just creates and nothing else happens..)
  4. so.. I selected "Use an existing SNS topic" and selected the recently saved topic
  5. Hit "Save" button
  6. Got the error

What am I doing wrong?

Thanks in advance

This seems to be a rather weird UI bug in the AWS console.

When you edit your pipeline to set the SNS topic, the select box for the pipelines IAM role is incorrectly set to -- Console Default Role -- (it should be Elastic_Transcoder_Default_Role. The entries beginning with -- probably shouldn't be selectable at all!)

enter image description here

Now, when saving the form, this will cause the error. This is not related to the selection of the Topic, as it might seem.

By changing the Role back to Elastic_Transcoder_Default_Role the error goes away.
