Answer 1

I experienced this issue when I was setting up an ECS cluster, task definition file, and service using Terraform.

It also happened at the point of deployment to an already set-up ECS cluster using Circle CI.

I get the error below when I run terraform apply or when I try to deploy using Circle CI:

An error occurred (ClientException) when calling the DescribeTaskDefinition operation: Unable to describe task definition.

Here's how I resolved it:

For Terraform:

The issue had to do with a typo in the cluster name that was not correct with how the service was referencing it. All I had to was to delete the name for the cluster name and had to retype it. This time the service was able to reference it correctly.

For Circle CI:

The issue had to do with a typo in the cluster name environment variable for the Circle CI project that was not correct with how the service was referencing it. All I had to was to delete the cluster name environment variable and I had to set the correct cluster name environment variable. This time the service was able to reference it correctly.
