Passing Task Outputs to Task Inputs Files not found

[FilBot3]

While following the Passing Task Outputs to Task Inputs tutorial, I am getting the error

files not found

After the image pulls down and inputs are copied to the container. From what I'm seeing, the file should be right where the tutorial is saying it is. All of the other examples have worked up until this point.

version: '3'
services:
  concourse-db:
    # https://hub.docker.com/_/postgres/

Just using the docker-compose.yml from the concourse/concourse-docker repo.
