Hey @wedlex,
Are you following the readme to use terraform and AWS or are you trying to do your own thing using that as a base? We list Terraform and AWS as required so anything outside of that wouldn’t be directly supported.
Looking at the Terraform runners it will copy the test file currently being used to /home/ubuntu/vegeta/tests which could be what you are missing, If you check n8n-benchmarking/main.tf at master · n8n-io/n8n-benchmarking · GitHub it covers where the files go and the env options being set then the runner that starts the script is here: n8n-benchmarking/start_script.tftpl at master · n8n-io/n8n-benchmarking · GitHub
May also be worth noting that it doesn’t just run run_test.sh it has some args as well.
