Bundle Cert with Lambda

I have a Certificate Authority file (.pem) that i’m bundling with my lambda and I have added the NODE_EXTRA_CA_CERTS to my environment variables with the path to the cert file. Unfortunately, when i make my requests back to my on-prem server, node is giving the following error:

My serverless.yml has an environment variable configured and it shows up with my lambda, for some reason, Node just isn’t picking it up. Doing this locally works:

      name: aws
      region: us-east-2
      runtime: nodejs12.x
      endpointType: regional
      stage: dev
        NODE_EXTRA_CA_CERTS: /var/task/.certs/My-Root-CA.pem
