AWS Codedeploy error: scripts/applicationstart.sh is not executable. Trying to make it executable

I am running Ubuntu on an EC2 instance and trying to set up code deploy to run scripts to provision the deployment in appspec.yml. However, these hook scripts do not seem to be running. When I check the code deploy error logs, I see the error message InstanceAgent::Plugins::CodeDeployPlugin::HookExecutor: Script at specified location: scripts/applicationstart.sh is not executable. Trying to make it executable.

This is very confusing because my scripts are very simple and I am not sure why they would not be accepted. Here is where they are called in the appspec.yml file:

version: 0.0
os: linux
files:
  - source: /
    destination: /home/ubuntu/teller-install
hooks:
  BeforeInstall:
    - location: scripts/beforeinstall.sh
      timeout: 300
      runas: root
  ApplicationStart:
    - location: scripts/applicationstart.sh
      timeout: 300
      runas: root

Here are the two scripts I am calling form this:

#!/bin/bash

cd /home/ubuntu/teller-install/Server && npm install
exit 0

And the second:

    #!/bin/bash

pm2 start /home/ubuntu/teller-install/Server/app.js
exit 0

The deployment succeeds but the scripts are not run.

Here is the error message i get in the codedeploy-agent log file:
