I'm trying to update my cloudformation template but the update is failing by giving the error:
      Updating Cloud Formation stack: cos-test
      Failed to create stack: cos-test. Reason: Detailed Message: Template format error: unsupported structure. (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: 4aacc0d3-5e9a-11e8-8941-055edca13c3c)
      Status Code: 400
      Error Code: ValidationError

      Also it's not showing in the console that the update failed.
      Tried to update the stack through my local CLI it works alright. Also I tested for any validation error through my local CLI, but there was no  error.

       

      I'm facing this issue only for the update stack and create stack works perfectly fine for my template.

          jai1806 burden50 Has there been any update on this? I've also got a deployment that works perfectly if I try deploy into Cloudformation directly - but when using Jenkins to deploy I get a:

          Comment [ Glad to see the issue is still open.  May 2020 and I'm seeing the same thing.  Hope someone's able to address this sooner than later.  (thanks) ]
