Sometimes the logs tab is empty and the instance creations fails bringing it to error state. How can i debug what went wrong and where? I am using Bluemix GUI to copy paste the terraform template.
Typically for a failed deployment in Cloud Automation Manager (CAM) you will see an error message in the deployment's Log File tab. However if you do not see anything on the Log File tab and did not receive an error message at time of deployment, first check the template formatting and then open a support ticket with IBM for further diagnosis. You can following the instructions at this link for contacting support.

The internal logs for Cloud Automation Manager will be reviewed by IBM support to help diagnose the issue. Thanks!
