Deployment failure, but no reason in log

We just experienced a deployment failure in production (ok in pre-production) and no information in the log about the reason exists. I’ve attached a screenshot and the raw log. Any ideas how to troubleshoot this?

Using v1.3.5.1564

Hi Jasper,

You can check the event viewer on the Tentacle for a reason. It will likely be because a variable substitution rule references a variable that isn’t defined for the scope.

If you upgrade to Octopus 1.5.1, these errors will now appear in the deployment log.
