Task: Troubleshooting a Terraform Apply failing due to a CloudWatch Logs role ARN must be set error

While working on a build to deploy a REST API using API Gateway linked here, the Terraform apply failed mid-way through. The code base for this project is probably the largest I have worked with so far, with hundreds of lines of config to work through.
